#paleoart, belated #FossilFriday

#FossilFriday Katie & I, hosted Dr. #ThomasCarr for the week. Fun times, and good to catch up. Known Thomas for 23+ years now. Time is stupid. Anyhow...we, in NO WAY, talked about #Tyrannosaurusrex or #Nanotyrannus the whole week. At all....really, I'm being serious....not lying whatsoever....

Lichens Are Beautiful!

There are two examples of lichen in the much younger Oligocene Baltic amber. The oldest fossil lichen is about 400 million years old (Devonian) from the Rynie Chert in Scotland. (Source: UCMP + refs therein).

Lichens are probably even older!

Looking back at your posts from last year, I see you were talking about Pi Day and a full moon with a lunar eclipse! 🌕 You also shared a cool megalodon tooth fossil for #FossilFriday. It's wonderful to see you continue to share fascinating things and strong opinions! Your voice and thoughts are so

#FossilFriday!

A large megalodon tooth set in Sterling silver, found in Tucson this year. It's a bit heavy. #FossilFriday

Welcome back to #FossilFriday

Here is the gastropod Worthenia koninck from the Upper Carboniferous (Pennsylvanian) Graford Formation in Lake Bridgeport, Texas. Worthenia is probably one of my favorite gastropods due to the fact that it has knobs around the shell which makes it quite ornamental.

Working on describing new polacanthid ankylosaur species from the lower Yellow Cat, basal Cretaceous, Berriasian. Got to playing around with my ilia overview fig. and it got out of control... So I guess, I got a bit more done on our ankylosaur character appendix as well for #FossilFriday.

Today, Amanda is 3D scanning our Hell Pig (Entelondont) skull (usually in the lobby display). We're going to use the 3D scan to restore the enormous snout kindly donated 2025 by the Leppart family.

Here UV light shows the skull is ~60% real.

Earth’s first major extinction was worse than we thought Fossil finds suggest nearly 80% of life on Earth died some 550 million years ago

Extraordinary new fossils from Newfoundland reveal an ancient mass extinction worse than the asteroid-driven calamity that killed the dinosaurs.

Photo of a small piece of dark grey mudstone covered with tiny flattened ammonite fossils preserved in dark brown pyrite.

#FossilFriday these Tiltoniceras (?) #Ammonites from Runswick Bay North Yorkshire, UK. There are layers of these several ammos deep, and many m2 in area in the black shales. My personal take is that they represent the maximum flooding surface and formed via condensation. #geology #paleontology

Stegosaurus, thagomizer end view. A mom and two girls pass byas they investigate a 180° diorama of the Jehol biota in the background. COSI, Columbus, Ohio.

Dinosaurs for #FossilFriday ! COSI teamed up with the AMNH to put together a permanent exhibit on dinosaurs a few years back. This Stegosaurus gets to gaze in wonder at the Jehol biota 24/7, at least when the lights are on. 🧪⚒️🦖🦕🪶 🧵

Thagomizer set to whackity!

Fossil plant (fern?) from the Kinney Quarry of New Mexico, Pennsylvanian age. I have 300 pieces I was assembling for a client who dropped the project. Anyway, if you're a paleobotanist, I'm looking to sell them at cost. May divvy it up later if I don't have someone who wants all. #fossilfriday

We love to see it! #fossilfriday 🧪

Is #FossilFriday still a thing? Anyway, here’s Burgessia from the MCZ collection at Harvard, imaged with laser- and LED-stimulated photoluminescence.

A worn dinosaur tooth of an indeterminate tyrannosaur, supposedly from the Judith River Formation in Montana, USA. Unfortunately, the provenance for this tooth is absent other than Northern Montana. #FossilFriday

Christening a new vessel with an inaugural flight can be unpredictable, so plenty of luggage in case of emergencies is essential.

The final frontier seems closer suddenly.

The weeks #Lego #FossilFriday is #Plesiosaurus

In 1821, Henry De la Beche and William Conybeare name a fragmentary fossil Plesiosaurus.

In December 1823, Mary Anning finds relatively complete fossil of Plesiosaurus.

#FossilFriday In 1787, Fray Manuel de Torres found near the banks of the Lujan River, the skeletal remains of a gigantic mammal. Cuvier gave it the name Megatherium americanum in 1796.

Dr. Thomas Carr is surrounded by #tyrannosaurs at MOR

Happy #FossilFriday! This week Dr. Thomas Carr is surrounded by #tyrannosaurs at MOR. Here he is examining some of the larger Tyrannosaurus specimens at the museum (#MOR555 on the left and #MOR008 on the right) to solve a tyrannosaur growth mystery.

#Fossilfriday: The hyaenid Dinocrocuta, from the Late Miocene of Eurasia and Africa. Dinocrocuta was much larger than living hyaenas, around 200 kg (440 pounds.)

Horse molar in vault at the science museum of Minnesota.

🐴 #CitizenScience #FossilFriday — Molar (SMM P77.20.1), specimen 8 of 12, was recovered in 1976. This story emerged from the landscape around St. Cloud, Minnesota, when P. Lansing collected this horse molar near Hgwy 23.

Before modern roads and cities, horses may have roamed Ice Age Minnesota.

Its #Fossilfriday the 13. Today an especially unlucky fish,
choked at its Prey. Length of the bigger fish about 3 cm.

This species, known from mid-Cretaceous French amber, is still of unclear affinities, and may represent a basal extinct lineage of cheliferoid pseudoscorpions. Size : unknown, maybe 5-ish mm of body length Time period : Late Cretaceous Paleoart speculativometer : Some Missing parts The animal drawn is a pseudoscorpion, an animal looking a bit like a mix of a mite body type with the pincers of a scorpion

What time is it? It’s #Cheliceratime & #Fossilfriday!
For this entry we're talking about an extinct french pseudocorpion, Heurtaultia rossiorum!
