I passed out some pdfs of this paper yesterday, but I'm thrilled to say that the Morrison Ankylosaur monograph is on line. Hopefully this will aid in folks needing Jurassic ankylosaur character states. giw.utahgeology.org/giw/index.ph... @utahpaleo-ufop.bsky.social @societyofvertpaleo.bsky.social
#FossilFriday Upper Albian Texasites (=Pawpawsaurus) vs basal Cenomanian Animantarx and Cenomanian Sivasaurus. The nodosaurid Texasites shares the medial premaxillary plate (pig snout) with the edmontosaurines, while absent (or weak) in Silvisaurus as in ?Borealpelta. Love ventral view of premax!
Hello #PortfolioDay!
I illustrate extinct animals and their environments.
A photo of a fossilized trilobite. The animal has a multi-segmented body and superficially resembles a horseshoe crab. The fossil is reddish in color.
It's Trilobite Tuesday! Modocia typicalis, a Middle Cambrian trilobite, can be found in an astonishing variety of calcified colorsβlike this red example. Beautifully preserved specimens have been found throughout Utah in vivid tones of black, red, brown, and tan.
Several lumpy baby sauropods with brown, striped skin hatch from white eggs in a barren landscape. Several adult sauropods, tails dragging and heads held high, walk off into the distance behind them.
Itβs my Hatching Day!

Two spiny trilobites with swept-back antennae, both metal, facing each other on a fossil-filled rock. On the left, the silver trilobite is a striking blue; on the right, the bronze trilobite is a warm...well, bronze color.
Trilobite encounter. Ceraurus species in sterling silver on the left, bronze on the right. One of my earliest experiments that worked; both have a liver-of-sulfur patina, but as you can see, if you time it just right, silver will pick up an incredible blue. #sciart
Spinosaurus aegyptiacus
An animal difficult to do justice with an illustration.
Digital illustration of an emperor penguin and Cryolophosaurus ellioti facing each other. Little bits of terrain are shown beneath each animal: the penguin stands on snow while the Cryolophosaurus is surrounded by some ferns (indicating the much warmer climate of Antarctica during the Early Jurassic).
Antarctic theropods π§
A troop of Ardipithecus on the run. One individual pushes its forelimbs off the ground, propelling the upper body upward. For a brief moment, one footstep is followed by another, arms flailing on the side before landing back down. Not yet.

Aerial view of a charcoal-colored trilobite fossil protruding from the surface of a mustard-colored stone. The trilobite has an oval-shaped body and a ribbed carapace. Its head is facing the top of the frame.
Itβs Trilobite Tuesday! Utahβs Weeks Formation is known for its variety of well-preserved Middle Cambrian trilobites. This 1-in- (2.5-cm-) long Meniscopsia is a seldom-seen genus. After more than a century of exploration and digging at this location, less than 20 complete examples have been found.

NZ has two genera: one lays eggs (Ooperipatellus, 1st photo) and another gives live birth (Peripatoides, 2nd). They also deposit sperm which burrow through their partner's skin, but that's another story! π§ͺ
Ancient critters
Close up profile shot of a pale-beige trilobite fossil facing the left of the frame. It looks rather small and has spiny-protrusions lining the sides of its oval-shaped body. On top of its head are a set of tall rectangularish eyes. The background is black.
Welcome to Trilobite Tuesday! Pictured is the Devonian-age phacopid trilobite Erbenochile erbeni. Not only does this Moroccan species feature towering 0.8-in (2-cm-) high eye stacksβeach topped by a unique shading brimβbut it also has a row of intimidating spines that run along its axial lobe.

Let's checkout a few mesoeusuchian grade terrestrial crocs from the Upper Jurassic (Kimmerigian)and basal Cretaceous (Valanginian) of the Colorado Plateau. The new Yellow Cat croc is twice the size of the 2 Morrison taxa. They filled role of skunks and racoons in mid-Mesozoic landscape.

A nice, pretty big lateral cervical spine from the basal Cretaceous polacathid n. sp. B was just prepared from a small jacket collected ~15 years ago at Jim's Place in the Doellings Bowl Bonebed about 15-20 m se of the other large polacanthid ("holotype") a second adult..?? #FossilFriday

A firefly squid (Watasenia scintillans) swimming in the dark. The top side is illuminated, letting you see its orange mantle, large eye and translucent white arms. The bottom is not illuminated, and only their glowing blue photophores are visible.

Firefly squids (Watasenia scintillans) have an absolutely stunning display of bioluminescence. Their bodies are covered in blue and green photophores.
They are also the only squid species known to have colour vision.
We CT scanned thousands of vertebrates from US natural history collections and made them freely available. Countless people have used the data for research (>200 pubs) and to learn anatomy/morphology.
