There is a story behind every sign.

Whoever made the MOR’s Saurornitholetes mount was working on the Stegoceras back in the day as well. Can’t remember the guy’s name.

Yes.

Did RCI make this mount? I saw it under construction in Livingston…

Nothosaurus skull almost done I think.

Flattened fossils in a pale sandstone showing a long, catshark-shaped shark from the Jurassic. Below are grey silhouettes of these body shapes and a palaeoart reconstruction of the shark in life

Check out our new #OpenAccess paper in @commsbio.nature.com redescribing bewhiskered Jurassic shark Bavariscyllium, led by Sebastian Stumpf. Although relationships hard to pin down, its catshark-esque form shows sharks explored varied body shapes from the start. 🦈〰️

Long museum case with complete phytosaur skeleton centered, larger phytosaur skull to the left, and some sort of slab to the right. Chalk drawings above.

Long musuem case with Lycaenops and dicynodont skeletons, assorted therapsid skulls on the wall

Square museum case with Allosaurus, Camarasaurus, and other skulls. Header says Jurassic Dinosaurs: The Morrison Fauna.

Museum case with partial Diplodocus skeleton. It's a pelvis with some dorsal and caudal verts on either side and one attached femur. A skull on a stand beneath.

Two white rhinos standing in front of a hut in ankle deep snow. The foreground features a juvenile while an adult stands slightly behind it.

A large white rhino standing in a snowy field, one leg raised slightly.

A white rhino plowing through the snow, its snout and horn are covered in snow, the head in general is wet and darker than the rest of the body.

Since it came up in a conversation I ended up googling if the rhinos in the Salzburg Zoo get out in Winter and not only do they, it also makes for some impressive photos

face of a sea spider, a marine arthropod. its body is very small and it is mostly legs. it has a long proboscis and two tiny brown eyes facing the viewer

look at this kind and friendly face and big silly nose

Platecarpus is a mosasaur, an extinct marine reptile with four flippers. This one is covered with colorful squares like a quilt, beginning dark teal at its back and fading towards light blue and yellow on the underside. Two Hoploscaphites, ammonite cephalopods, are swimming nearby.

Out now: latest addition to the Grande volume! Guang-Hui Xu reevaluates Guizhoubrachysomus from the Middle Triassic of southern China. Interpreted as a "luganoiid" in the past, this work argues Guizhoubrachysomus is instead an early dapediid, a group most famous from Jurassic deposits of Europe.

The skull of an extinct bird with a long, curved bill. Close-ups show features relevant to interpreting its sensory biology.

I was asked yesterday to post a walkthrough of Life Over Time, the shortest-lived and generally weirdest iteration of the Field Museum’s fossil halls. If you visited between 1994 and 2004, this is the version you saw. I’ve got some time, so let’s do this.

Adaptive radiation of pelagiarian fishes at the K/Pg boundary led to rapid diversification of mandible morphology Abstract. Mandibles represent a key evolutionary innovation that has enabled jawed vertebrates to adapt and diversify in response to a range of food source

New paper! Here we look at shape evolution of the mandible in Pelagiaria, a group of open-ocean fishes that includes tuna and mackerel. We find that shape disparity accumulated rapidly at the origin of the clade at around the K/Pg boundary... academic.oup.com/evlett/advan...

A snowflake eel CT scanned skeleton. it has scary extra jaws behind its skull that look like a bow with teeth.

Finally have time to upload things to Sketchfab.

Here's the dead eel I found at an aquarium store!

Thanks to the generosity of the store owner, everyone can see the scary extra jaws these guys have!

Wow, look at how detrimental an effect world wars 1 and 2 had on the progress of taxonomy. Not the type of signal I thought I’d see.

Claim: The cost of living is low. True: The cost of living is much lower than what it will be in a few months.

A digital painting depicting an ancient underwater predator called a mosasaur with a shark in its mouth. The ocean is blue, however red blood is coming out of the shark's mouth. A school of small fish are eating the blood while diving aquatic birds hunt after the fish. Rays of sunshine filter through the water screen right.

A large mosasaur finds a meal in a Komoksodon kwutchakuth. Named in honour of the K'ómoks people of BC and the word for shark, kwutchakuth, in the Comox language. The diving birds are Maaqwi cascadensis whose fossils were found on Hornby Island here in BC. Ma'aqwi means "water bird" in Coast Salish.

We can all relax now, ROM put out some press photos over the weekend!

Basically, the space between the Jurassic/hadrosaur hall and the T. rex/Cenozoic hall has been opened up, and now houses the real Zuul fossil plus the cast Gorgosaurus vs Zuul created for a temporary exhibit in 2019.

An (ecto)parasitic #Crustmas. This is Dolops (above), which swims around and attaches to fishes (below), but unlike its relative Argulus, which has suckers, it has hooks to hold on. Also, is bizarrely cute!

A macro photo, front three-quarter view, of a little butterfly perched on a green leaf. The butterfly has pale green eyes with black speckles, legs covered in thick yellow fuzzy hair, and orange wings sprinkled with metallic light blue patches. It is very cute.

A macro photo, side view, of a little butterfly perched on a green leaf. The butterfly has pale green eyes with black speckles, legs covered in thick yellow fuzzy hair, and orange wings sprinkled with metallic light blue bands and patches. It is very cute.

Please enjoy this ridiculously cute butterfly, which was about the size of my pinkie fingernail. It's in the butterfly family called metalmarks (Riodinidae). Males, like these, have reduced front legs and perch using only the rear 4 (females can use all 6). Sarota acantus; Costa Rica 🐙🌿 #insects
