I used [link] 's skeletal reconstruction as a base and the colored scheme is totaly imaginary though a bit reminiscent of a sparrow's. Maybe I'll have to update once they found the color scheme of this little fellow.

Also I'm not sure of what the extent of Aurornis's plumage was so I based it on Archaeopteryx's.

Comments and constructive criticism are welcome. ]]>

Well, the manuscript is accepted so here is the 2nd in the series.

ca. 235,000,000 bp, uppermost Middle Triassic (late Ladinian), Xingyi County, Guizhou, China (Zhuganpo Formation).

A coastal reef at the very end of the Middle Triassic. We're close to the shores of a large island, over 100 km off the South Chinese mainland. Sleek and deadly, a nothosaur snacks on it's abundant smaller relatives, the keichousaurs, ducking beneath the incredible neck of Tanystropheus to do so. Other reef denizens flee in terror while ammonoids and wing-finned Potanichthys hover unconcerned in the surface waters.

MARINE REPTILES
Nothosaurus youngi - (big yellowish foreground predator) 2.1m long. Nothosaurs were the most badass predators of the Triassic seas. N. youngi was one of the smaller members of it's genus but still formidably armed with wicked-looking teeth.

Keichousaurus hui - (numerous small reptiles in foreground) Under 30cm. by far the most abundant tetrapod in the Xingyi biota, known from hundreds, if not thousands, of specimens ranging from embryoes to adults.

Yunguisaurus liae - (pair of long-necked swimmers in background) Up to 4.5m long. the Middle Triassic sauropterygians most completely adapted for aquatic life were pistosaurs like Yunguisaurus. Their long-necked, paddle-limbed body configuration was a winning formula that was taken to extremes by their plesiosaur descendants later in the Mesozoic.

Tanystropheus cf.longobardicus - (huge long-necked reptile stretching into foreground) 6m long, over half of which is neck. Remains of this preposterously long-necked protorosaur from Xingyi include an almost complete skeleton that is effectively indistinguishable from T. longobardicus from Italy and Switzerland - unfortunately the head is missing on the Chinese specimen so we can't be totally sure. A predator of cephalopods and small fish (based on gut contents of European specimens), the body of Tany shows no obvious adaptations for marine life. However it's pan-Tethyan distribution and presence at Xingyi, 100s of kms from the nearest continental landmass, suggest considerable maritime capabilities.

Anshunsaurus wushaensis - (serpentine reptile in background) 2.5m long thalattosaur with a small ichthyosaur-like head. At this time thalattosaurs were rare in the region and not very diverse, however the group was about to come into their own within a few million years.

The apparent absence of ichthyosaurs at Xingyi is puzzling...

FISH
Peltopleurus orientalis ­- 5cm, numerous small brown fishes.
Guizhoubrachysoma minor - 4cm, short, blue fishes.
Guizhouamia bellula - 15cm, slender fishes with orange stripes. Originally described as the world's oldest bowfin (amiid). It isn't.
Asialepidotus shigyiensis - 20cm, brown fishes with vertical bands. Guizhouella/Guizhoueugnathus analilepida is a synonym.
Potanichthys xingyiensis - 15cm, big-winged fishes near the surface. The most famous of the Xingyi fishes, Potanichthys was one of the first attempts at flight by the Actinopterygii with many convergent similarities in fin shape and body form to modern flying fishes.

INVERTEBRATES
Schimperella acanthocercus - 4cm minus antennae. numerous small shrimps. Yes, I think Japanese crystal red shrimps are cool. Probably the most common fossils at Xingyi.
Protrachyceras sp. - ammonoids.
Traumatocrinus hsui - floating colony of crinoids in the far distance. Rare at Xingyi, as with the thalattosaurs, these huge echinoderms would become far more common within a few million years. ]]>

Wow, this took far too long to complete! But then again, it started as a doodle idea for me to relax while working on...

That sloth in the foreground has changed so much! I sketched him without a reference and originally thought about giving him a cartoony face: [link] Glad I went with realistic in the end.

Otherwise not much to say about this. Just a trio of three-toed sloths in a fantasy jungle of shiny plants and big yellow mushrooms. Their fur is fun to paint/draw.

With a century of hind-sight available I'm not convinced this was a good idea. While it's obviously hard to compare much between the two animals (the AMNH specimen lacks any limb material, while the Carnegie specimen is missing almost all of the neck and tail) they still show off some interesting differences. The pelvis of the type specimen really does come across as rather robust (the pubis seems to match Sue's in heft), but oddly the skull appears to be slightly shorter (based primarily on the lower jaw),

This could easily be chalked up to individual variation (compare your average NBA player with Jay Leno and you see far greater diversity), but it does emphasize the importance of looking at individual specimens in a species, rather than assuming you can mix and match them at will.

P.S. I know many of you care about size estimates. Hopefully it's clear that we have no way of knowing which of the two specimens was actually larger, given how much is missing. I gave a very slightly longer estimate to the CM specimen because that's what I come up with, but that's assuming a tail that is similar in proportion as the AMNH specimen, and as we just discussed that's not necessarily a safe assumption. ]]>

Cool stuff. It is heavily implied that they were herbivorous, and recent analysis of tooth wear and jaw anatomy suggests that this was the case for this animal. That's right: herbivorous crocs.

Many of the colors and designs of this piece were based on New England tide pools. The Leiopteria, for example, are colored and clumped like Mytilis edulis, the common blue mussel of the Northern Atlantic. Additionally, the pink-gray background is a crustose coralline algae similar to the "bubble gum crust" Phymatolithon lenormandii which is common on intertidal rocks in New England (coralline algae possess a "skeleton" of calcium carbonate).

The dark purple seaweed along the edge is meant to resemble Chondrus crispus, a red algae that possess a blue iridescence when underwater.

The small yellow creatures in the bottom left are trilobite larvae called protaspids. Little more than headshields at this point, the protaspids will grow new body segments with each molt. ]]>

specimen 010

STYGIMOLOCH SPINIFER
"Horned Devil from the River of Death"
Galton & Sues, 1983
Length: 3m (10ft)
Weight: 90kg (200lb)
Location: Montana, USA
Era: Maastrichtian age, upper Cretaceous (65 million years ago)

Classification:
Dinosauria
Ornithischia
Cerapoda
Marginocephalia
Pachycephalosauria
Pachycephalosauridae
Pachycephalosaurinae

Notes:
Recent analysis may indicate not only that the similar (but flat headed) Dracorex hogwartsia may be a juvenile Stygimoloch, but that Stygimoloch itself may be a juvenile form of the contemporary Pachycephalosaurus wyomingensis.

Synonyms:
Dracorex hogwartsia? Bakker et al., 2006

UPDATE APR 30, 2013:
An old one I wanted to update a bit for a while. The feet always looked wrong to me, so they were completely redrawn, as were the hands. The lineart overall was touched up here and there. Not a major update, but an update nonetheless. As a side note, while I will be keeping this page and animal labeled "Stygimoloch," I no longer believe it to be a valid taxon. Had I done the project with what I know now, I would have done Pachycephalosaurus proper in its place. Go here ([link]) for the original Stygimoloch drawing and compare. ]]> project: DINOSAURIA

Depicted in the lower illustration is Hemisaurus latognathus, meaning wide-jawed half lizard, a reference to the fact that only the front half of the animal was preserved in the fossil. Like most Anguillasaurids, Hemisaurus had no limbs whatsoever, and swam by undulating from side to side like an eel. It was recently discovered in the Amazon Formation, known to be a tropical freshwater environment with abundant swamps. Its specific name does not reference the shape of its actual jaw bones, but rather the fact that the individual jaw bones may have been able to separate and swing outward, giving the aquatic reptile a very wide bite. Here I depict it with an inflatable throat pouch, which would swell up with water when Hemisaurus suddenly opened its mouth, vacuuming in prey such as this Cacumenodon (a bizarre boneless fish known from many sets of teeth and a single soft-tissue impression).

Above is an even more speculative reconstruction of Acudontosaurus eremicus, another Neogene Anguillasaurid. Bizarrely, this species was found in deposits formed in dry environments in what was once North America. Some suggest that it may have been caught by a predatory animal and then adbandoned, or that it was left stranded there by a brief freak flood, but there is no fossil evidence for either of those conjectures. What if, perhaps, it was a burrower? That would also explain its blunt, shovel-like skull shape. The other strange feature of Acudontosaurus is the huge, curved pair of fangs for which it was named. I think it's possible that it was not a predator but a blood sucker, using its fangs to pierce flesh and gripping prey with its separated lower jaws. As seen here, it lifts its head from its burrow to look around, perhaps to find a sleeping Iugotherium (the large contemporaneous herbivore I drew) to feed off. ]]>

The only thing i dont like is that because i ran out of room on the paper, the tail is a bit shorter than it should be. nevertheless i had fun making this! the flesh version is of my speculative opinion. Because a mane of quill/feathers seems cool.

Update: I just added another layer of feathers. It's interesting how the secondaries and tertials concealed the upper leg (from the front only two leg segments are visible, as in a modern bird).

Update: Pennaceous feather fans added to legs. Photo quality is a little icky, when I get my real camera working I'll redo it. But this is more or less it's final state. ]]> [link]

In the understory, the "coral-bush" organisms are colonial flagellates (Hyalobryon ramosum) and the larger, solitary tube-dwellers are Stichotricha secunda. The lumpy yellow balls are testate amoebas (Pseudodifflugia gracilis), which build a hard shell out of cemented sand grains.

The giant floating "planets" are colonies of proterospongia choanoflagellates-- which may be the ancestors of sponges and, by extension, all multicellular animals.

The plesiosaur-like organisms wimming through the the middle are two species of "trunked" ciliates. The green ones are Lacrymaria olor and the blue are Dileptus anser. Both ciliate species possess a long flexible "trunk" that they snake through the sediment in search of prey. In real life, both ciliates inhabit the muddy sediment, but for this piece I used a bit of artistic license and made them into free-swimmers. On the ground below the two Dileptus is a "trunked" amoeba (Oscillosignum proboscideum) that can produce an elongated pseudopod to search for food in the same manner as the ciliates.

Go here: [link] and here: [link] to see some cool real-life videos of trunked ciliates.

To the right, the brown, cymbal-shaped "creature" is actually a mobile colony of bryozoans (Oscillosignum proboscideum). The colony's "legs" are actually highly modified zooids called "setiform avicularian mandibles".

In the bottom center of the piece, just below the Oscillosignum amoeba are three testate amoebas (Arcella vulgaris) that have an unusual method of flipping over. If an individual Arcella is knocked onto its back, it's pseudopodia cannot reach around its shell to touch the ground. To right itself, the amoeba secretes a gas bubble into one end of its shell, thus raising that end up and tilting the pseudopodia over far enough so that the organism cna grab hold of the ground and right itself.

The two odd spiny-mask looking ciliates floating through the sky in the upper left are Discomorphella pectinata. ]]> The strange, tree-like structures are tube-building Floscularia rotifers.
