The Archosauria: _Euparkeria_!

Parker’s Good Animal: Euparkeria capensis



It may seem strange to admit an animal into an art show called The Archosauria that isn’t an archosaur, but under the definition chosen for the show (the Archosauria being comprised of the most recent common ancestor of birds and crocodiles and all of their descendants), Euparkeria is not actually a member of this group.

It is, however, very closely related to archosaurs -- belonging to a sister group to the Archosauria. Because it is so basal, Euparkeria can be regarded as a transitional form linking archosaurs to broader, more inclusive diapsid groups. In that sense, Euparkeria is so close to the genesis of a nearly quarter billion year long dynasty of reptiles that encompasses crocodiles and birds and everything else that evolved between them that it would seem foolish not to include it.

Those beginnings were certainly humble enough: Euparkeria is a small, lightly armored animal, no bigger than a housecat, which lived in Gondwanaland in the Early Triassic (about 248-245 million years ago, in what would become southern Africa). Euparkeria may have eaten insects or dined on smaller vertebrates while evading larger predators.



Media & Commentary:

Many, many pencil sketches went into this, and I think it's safe to say almost none of them are ever coming back out. Many ideas were thought of and then discarded, due to time constraints/difficulty. As such, I'm still sort of wistful whenever I think of it. Still, in spite of the disappointments, this is the strongest piece I produced for our little show.

Oils on canvas. Sorry some of the paint is still a bit shiny (possibly I could have photographed it a bit better as well). At one point I think I was working on three pieces (oils) at once, and things are still somewhat not-dry on any of them.

The Archosauria: _Stomatosuchus_!

Stomatosuchus inermis: Unarmed Filter-Feeding Crocodile




What a pity Ernst Stromer’s poorly-known Eusuchian’s remains did not survive WWII, as it is one of the only known filter-feeding crocs. What material was known was a long skull, with a blunted snout (in a similar manner to alligator snouts), filled with hundreds of tiny teeth in the upper jaw and no teeth in the mandible. Assuming what is known about ratios between head length and body length for crocs is true for Stomatosuchus inermis, then Stomatosuchus grew to 12 meters (over 40 feet) in length.

The lower jaw suggests Stomatosuchus may have had a large throat pouch (perhaps like a pelican), useful for capturing, then filtering its prey from the water.

Stomatosuchus filters like an Egyptian: known from upper Cretaceous deposits in Egypt, this material was destroyed in an Allied bombing raid in 1944.



Media & Commentary:


What a pain oils on canvas board turned out to be. The background consisted of layers and layers of pigment washed with linseed oil, and this caused the whole of it to curl aggressively. The deflection caused by the oils made working on it not only annoying, but it was exacerbated by the fact that I was trying to accelerate drying time by placing it into the oven for short periods of time.

This was a mistake. I had to take it to a framing shop to flatten it, and then frame it to prevent it from curling even more.

Two and a half weeks were spent in total on this. And this was one of the last essays written, so I was a mite punchy at that point.

Portrait of the Underpainting

I actually painted this a few weeks ago, but got all caught up in moving (also in progress).

Euparkeria goes in the middle.
