South Dakota School of Mines Museum of Geology

Recently completed a field camp course hosted by the South Dakota School of Mines and Technology. There were many magnificent sights to see out there in Wyoming and South Dakota, but having to regularly scramble up and down rock outcrops did not encourage the use of my good camera. Additionally, photography tends to take a backseat when you are being graded for your field work, the net result being that I only have a handful of relatively low-quality photos from field camp proper. However, once the course was done, I got the chance to visit SDSMT's own Museum of Geology, at which I was free to be more shutter-happy. Despite the small size of the display area, the museum's collection was quite impressive. It was also nice to see an exhibit on conservation paleontology.

A row of skulls showcases the evolution of that iconic North American megabeast, the American bison.

Most of the specimens displayed here were discovered at local fossil sites (some of which we worked at during field camp). Here is a skull of the nimravid Hoplophoneus with a painful-looking bite mark.

Smilodon compared to living cats, including (clockwise from top left) a house cat, a bobcat, a clouded leopard, and a mountain lion.

More Hoplophoneus skulls.

This is a specimen that had to travel some ways to get here, a juvenile Mauisaurus.

The centerpiece of the museum was a mount of another plesiosaur, Styxosaurus. It was so big that it was essentially impossible to fit it all in one shot.

The skull of Archaeotherium, a hell pig (but not really a pig).

The foot of the hornless rhino Subhyracodon.

The skull of Subhyracodon.

Protoceras, a member of an extinct radiation of North American artiodactyls with bizarre headgear.

How many universities have their own Tyrannosaurus rex?

A Mosasaurus mount. Spot the palatal teeth!

The skull of the amphicyonid Daphoenus.

A glass case showcased brontothere sculptures by Charles Knight.

A partial skeleton of an Oligocene snake.

A full-body mount of Archaeotherium.

Leptomeryx, a small ruminant.

An oreodont mounted with unborn young in its womb.

A gomphothere skull.

The brontothere Brontops.

Ah, a maniraptor! Procrax, a fossil cracid fowl.

A mount of Edmontosaurus (or is it Anatosaurus?).

Glad that they acknowledged that the mount is in an outdated posture.

Should be "femora"!

The skull of Triceratops.

Mosasaur stomach contents.

Considering the ubiquity of cannibalism among modern carnivores, "mosasaurs probably were NOT cannibalistic" is a bold claim to make.

A partial skull of the mosasaur Hainosaurus.

Mesosaurus, not a mosasaur.

There was a screen playing Valley of the T-Rex [sic]. Ehh.

Vintage Dinosaur Art: Predatory Dinosaurs of the World - Part 3

Who asked for one more round of Predatory Dinosaurs of the World? No? Well you're getting it anyway. If it's any consolation, you might not have expected to see Dimetrodon and Eryops showing up in a book with such a title, and yet here they are. Pesky Dimetrodon, always sticking its giant fin in where it isn't welcome.



Naturally, these Permian beasties appear in a section providing the background and overall evolutionary history of theropod dinosaurs, a chapter replete with wonderful illustrations like this one. It's intriguing to see Greg Paul take on animals other than the ones we're used to seeing, and the results are predictably very lean-looking, although it's lovely to see Dimetrodon being so energetic (and definitely not marking its territory, no matter what Thomas Diehl might think over on the Fezbooks). This is also a notably richly illustrated Permian scene, with an assortment of fauna swarming over an imposing forest - as opposed to a blasted sand dune with a few generic fronds scattered here and there.


Many readers will recognise the above piece from Paul's 2010 Field Guide to Dinosaurs (second edition coming soon!). Aside from the forelimbs, it's aged rather well - Paul's style probably suits Coelophysis more than any other dinosaur (after all, it's an animal that has literally been rendered as pair of rubber-coated pipe cleaners before). Note both the Bakkerian neck plumes and mixture of 'robust' and 'gracile' morphs. It remains an exciting and energetic piece, as a marauding gang of unnervingly gangly, long-necked theropods round a bend to confront the viewer.


On to the Jurassic, and a reclining Allosaurus (Mark Witton would approve) watches Camarasaurus, Diplodocus and Stegosaurus around a watering hole. This piece is all the more effective for presenting the scene from a human's eye view, as if Paul drew it from life (which Mark notes is a very effective palaeoart technique in Rec-a-Rep). It's nicely composed, with a good variety of animal life on show (there's more than just dinosaurs here), and the context is entirely naturalistic, recalling layabout lions eyeing giant African herbivores as they gather to drink. If there's one bothersome aspect of this, it was what Niroot pointed out to me - namely, that the way the Diplodocus' tails pivot up into the air is a little strange. They're on a slope, sure, but why does the tail stick  up to oppose the head and neck, like a see-saw? Wouldn't it just stick out behind, given that they have a solid quadrupedal base to stand on? Nitpicking, though - this is a fantastic piece, one of the best in the book.


As the Late Cretaceous draws in, so we are treated to rampaging tyrannosaurs making a nuisance of themselves. Again, we have a wonderful mix of herbivore behaviours. The less well-defended hadrosaurs Kritosaurus and Hypacrosaurus scatter to the left, dodging Edmontonia (just visible on the scan) which is notably less concerned. Meanwhile, the ceratopsians Chasmosaurus and Centrosaurus act like belligerent, overgrown bovids, confronting the threat and brandishing their horns. It'd be a foolish Daspletosaurus that took on such a foe. Such well considered, exciting pieces like this demonstrate why Greg Paul still deservers a place at palaeoart's top table.

Interestingly, the huge pterosaurs shown here are Quetzalcoatlus, and they're much closer to their 'modern' look than many other artists managed at the time (most of whom were, admittedly, busy copying Sibbick's nubbin-headed beast). They share the sky with modern-looking birds.


There's some other cool stuff which I haven't featured yet that doesn't appear in the aforementioned chapter (A History of Predatory Dinosaur Success and Failure, and of their Avian Descendants, should you have been wondering), so I'm going to tack it on artlessly here. Here, the frankly quite bonkers-looking Mamenchisaurus hochuanensis is confronted by Yangchuanosaurus shangyouensis, which Paul lumps into Metriacanthosaurus for some reason. One of the allosaurs has sliced some flesh from the sauropod's thigh. Intentionally or not, the two tiny pterosaurs flying past the sauropod's neck are reminiscent of old palaeoart pieces, where they were used for scale - in particular, Zallinger's The Age of Reptiles mural.


Having said that, Paul is very keen on busting old palaeoart tropes where appropriate. In Paul's own words,
"Far from trying to escape into water for safety, herbivorous dinosaurs were in dire danger if caught by packs of swimming theropods, as is the case with this Apatosaurus louisae, surrounded by Allosaurus atrox [probably just A. fragilis]."
It's a classic cutaway that's been imitated many times since. Judging by the signature, it was originally drawn in 1980. One can easily imagine how revolutionary it must have seemed at that time.


When not bandying iffy taxonomy and confusing terminology about ('brontosaur' as an alternative term to 'sauropod', as opposed to referring to a particular type of sauropod? Huh?), Paul was often far ahead of everyone else in terms of the quality of his reconstructions. Anomalous vestigial finger aside, his Baryonyx (above) is much better than many others at the time, some of which sported piratical appendages on the end of their arms.


I'm sure I've said previously that I'm so very happy that ornithomimosaurs were found to have had a feathery covering. They just make so much more sense with one. Once the more jobbing dino illustrators catch on, and once tight-arse publishers stop reprinting crudely modified Sibbick illustrations from the Normanpedia (31 years young!), we'll finally be rid of the creeptastic, tiny-handed, stilt-legged, prune-skinned monstrosities of the '80s and '90s once and for all. Of course, Greg Paul got there first. GSP was right! Tell the children!


...Except, of course, he wasn't always. I'll leave you with this charming skeletal diagram, depicting a composite therizinosaur transformed into Plateosaurus-meets-Edward Scissorhands. Why would I finish a celebration of Paul's triumphs with this unfortunate guess-too-far? Because I am, in the end, a right bastard.

Next time: life-size fibreglass dinosaurs return to LITC, with guest star Dave Hone (for it is he)! Oh, yes.

Recreating an Age of Reptiles: Marc's review

While recent years have seen a number of books that celebrate palaeoart for its own sake (rather than featuring it in a purely illustrative context), not enough of them feature explanations by the artists as to why they made this or that choice when restoring long-dead animals. Why that colour pattern? Why that crest of scales? Why that unusual plumage distribution? Informed speculation is an absolute necessity, but it doesn't mean that (good) palaeoartists are just pulling the lever on an extinct beastie fruit machine and cobbling together the results. Perhaps the best aspect of Mark Witton's new book, Recreating an Age of Reptiles (aka Rec-a-Rep), is that Mark consistently provides the informed thinking behind his speculative choices, as well as explaining the science that forms the foundation of all his art. It's easily one of the best palaeoart books in years, and not just because Mark's artwork is often very lovely.

Images copyright Mark Witton, used with permission. Remember, "there's a special circle of hell...located halfway up Satan's bottom" for art thievin' types. (And book pirates.)

Mark's also keen on busting tiresome palaeoart tropes, but not at the expense of producing art that lacks aesthetic appeal. For all his depictions of theropod dinosaurs lounging around, sauropods threatening each other with body language, and swimming pterosaurs, this was perhaps most evident for me in his chapter on Mesozoic synapsids. Traditionally depicted cowering at the scaly feet of their saurian overlords, Rec-a-Rep gives these animals a chance to take centre stage in a series of visually arresting images. The Early Jurassic cynodont Kayentatherium is shown tenderly carrying a juvenile back to its burrow, a behaviour inspired by the parental tendencies of modern mammals, while the 'dinosaur killer' Repenomamus is shown in an atypically peaceful context, rolling in the leaf litter while sporting a fetching stripy coat.

Mark acknowledges that the above piece, featuring the tiny Middle Jurassic Stereognathus, is more typical of art featuring Mesozoic synapsids; after all, it features tiny, vulnerable, superficially shrew-like animals emerging after dark, with vastly larger theropod dinosaurs lurking in the background. However, and as Mark points out, the piece is enhanced by the striking, high-contrast colouration of the Stereognathus, and the wonderful use of light and shadow. Mark explains that his approach is to try and make animals appear striking without resorting to garish colours; after all,
"...modern animals show that they can be attractive, intricate-looking species without brilliant or vibrant colours...Palaeoartists often default to bright, even garish colours to make their animals appear engaging, but it might be that high-contrast patterning is a better supported way to create arresting but believable restorations."


Mark discusses believability a great deal; the art of going beyond a restoration that is merely scientifically plausible, to something that looks like it could have been painted from life. He contends that as palaeoartists, we needn't worry about our work becoming outdated - it is enough that we provide an easily understood and appealing snapshot of the state of the science at the time the piece was made. It's a combination of these factors that has kept the work of the 'Old Masters' of palaeoart (Knight, Zallinger, Burian et al.) appealing even today. Mark makes an effort to present prehistoric animals in an 'everyday' context. The Sinornithoides in the above piece, excellently composed around a skeletal tree, are typical in that they aren't dramatically fighting or devouring anything. They also sport precisely the right amount of speculative decorative plumage and intriguing colouration to make them believable as living creatures, painted by an artist sitting in a deckchair in Early Cretaceous Mongolia.


Naturally, Mark is as influenced as everyone else by All Yesterdays (which is duly namechecked here), but unlike some artists he has not seen that book as an excuse to unleash all manner of brightly-coloured silliness, or dress dinosaurs up as modern animals (except for those pigeon-therizinosaurs, mind). Further, his homages to the Old Masters will be greatly appreciated by any fan of classic palaeoart, and show his appreciation for the genre's history as much as the cutting edge. His Machairoceratops piece (above) might seem thoroughly modern, with its gloriously spiny and studded ceratopsians, but Mark explains that these features are a tip of the hat to Charles Knight's 'Agathaumas'. While tributes like this are made explicit, I can't help but feel that Mark also unconsciously apes the 'Old Masters' in a number of other pieces, which have a strikingly retro air in terms of composition and technique (and believability), while also featuring up-to-date reconstructions.


I would point to his most recent Spinosaurus reconstruction (above) as perhaps the best example of this. The painterly quality of this piece - along with the ponderous appearance of the giant spinosaur - harken back to the palaeoart of old. (Of course, one can well imagine that Spinosaurus was indeed very ungainly when on land.) In Rec-a-Rep, this piece is used alongside an older Spinosaurus reconstruction to illustrate how quickly our views of prehistoric animals can change, and apparently unassailable restorations can be rendered obsolete. This is also, naturally, a chance to indulge in one of my favourite pieces in the book, depicting a Crystal Palace-style Iguanodon alongside some super-cute chubby babies. (Evil Richard Owen with pith helment and elephant rifle not included.)


So, yes, this is a gorgeous and very important book. It's significant in presenting an artist-scientist's stunning palaeoart alongside not only an exploration of the background and influences behind each piece, but also a discussion of palaeoart - its history, its issues, and its place in palaeontology and science outreach. But mostly it's about really great palaeoart, and how it's made. A real must for anyone who regularly enjoys Mark's art, writing, and palaeoart in general, past and present. And yes, there are azhdarchids, too.

In the News

Cool news regarding a shared origin of feathers, hair, and scales: Nicolas Di-Poï and Michel Milinkovitch of the University of Geneva have published research tracing them all to the shared ancestors of modern birds, mammals, and reptiles. It all has to do with placodes, thickenings of the skin in embryos which had until now not been observed in developing reptiles, though the same genes had been found to control these three forms of integument.

Paleoart Pick

Mark Witton's long-awaited book of palaeoart is out now! Pick up Recreating an Age of Reptiles at Lulu. Sit back to enjoy this launch video from Mark.

I love how he expressed the idea of "credibility" in palaeoart. His point that many depictions of prehistoric life can depict equally valid hypotheses is in line with my feelings over the past few years. Wouldn't it be great if at least some palaeontology press releases or media coverage included multiple reconstructions, driving home the point that there are no concrete answers for many of our questions? Anyhow. Pick up a copy of the book.

In Fact, Mrs. Clinton Did Lie to the American People©

Introduction: The debate about Hillary Clinton’s email scandal brought forth from her numerous categorical denials. Her opponents have claimed that she lied in many of these instances while her supporters, among them a friend of mine, maintain she has been honest throughout the ordeal.  This morning FBI director James Comey issued a report on their investigation and flatly contradicted Mr. Clinton and showed her to in fact be lying to America about six issues which I have listed below.


1.  She said: she never received any email that was marked classified.

Comey said: “From the group of 30,000 emails returned to the State Department in 2014, 110 emails in 52 email chains have been determined by the owning agency to contain classified information at the time they were sent or received. Eight of those chains contained information that was top secret at the time they were sent; 36 of those chains contained secret information at the time; and eight contained confidential information at the time. That's the lowest level of classification.”

2.  She said: she turned over all work-related emails to the State

Comey said: “ The FBI also discovered several thousand work-related e-mails that were not among the group of 30,000 e-mails returned by Secretary Clinton to State in 2014.”


3.  She said: she never knowingly sent or received classified information on her server.

Comey said: “...there is evidence that they [Clinton and staff] were extremely careless in their handling of very sensitive, highly classified information.

For example, seven e-mail chains concerned matters that were classified at the top secret special access program at the time they were sent and received. Those chains involved Secretary Clinton both sending e-mails about those matters and receiving e-mails about those same matters.

There is evidence to support a conclusion that any reasonable person in Secretary Clinton’s position or in the position of those with whom she was corresponding about the matters should have known that an unclassified system was no place for that conversation.

In addition to this highly sensitive information, we also found information that was properly classified as secret by the U.S. intelligence community at the time it was discussed on e-mail. That is excluding any later up-classified e-mails.

None of these e-mails should have been on any kind of unclassified system.”


4.  She said: she only used one device and had one server

Comey said: “It turns out to have been more complicated than that. Secretary Clinton used several different servers and administrators of those servers during her four years at the State Department, and she also used numerous mobile devices to send and to read e-mail on that personal domain.”


5.  She said:  her personal server(s) were secure

Comey said: "We also assess that Secretary Clinton’s use of a personal domain was both known by a large number of people and readily apparent.

She also used her personal e-mail extensively while outside of the United States, including sending and receiving work-related e-mails in the territory of sophisticated adversaries. Given that combination of factors, we assess it is possible that hostile actors gained access to Secretary Clinton’s personal e-mail account."


6.  She said: she did not violate Federal law

Comey said: “ there is evidence of potential violation of the statutes regarding the handling of classified information”

Let’s think together again, soon.

Note:  You may read Comey’s complete statement here:

How To Understand Foundation Colors via Color Theory

*Post originally written by Olivia J on The Unknown Beauty Blog. If you see this post elsewhere, it has been stolen.*


Creating foundation colors is harder than creating just the normal color for painting because you are dealing with matching a color to a living organism with many variations.  However, there is a set calculation and that is color theory.
