Ptero firma: Footprints pinpoint when ancient flying reptiles conquered the ground
Study links fossilised flying reptile tracks to animals that made them

#Fossils of footprints over 160 million years old have helped palaeontologists at the University of Leicester to narrow down when #pterosaurs adapted to live on the ground.

EurekAlert!Ptero firma: Footprints pinpoint when ancient flying reptiles conquered the ground- Study led by the University of Leicester links fossilised flying reptile tracks to animals that made them - Fossilised footprints reveal a 160-million-year-old invasion as pterosaurs came down from the trees and onto the ground - Tracks of giant ground-stalkers, comb-jawed coastal waders, and specialised shell crushers, shed light on how pterosaurs lived, moved, and evolved

terrible lizards, by @dave_hone and @iszi , has released a wonderful interview with Dr. Rebecca Hunt-Foster, paleontologist and curator at the US Dinosaur National Monument.

@dantheclamman , there are freshwater clam fossils in in the quarry with all those dinosaurs, but there are apparently no fish fossils! What the heck!

terriblelizards.libsyn.comTerrible Lizards: TLS11E04 Curating DinosaursWe have talked about all manner of fundamentals of research on fossils over the years here on Terrible Lizards, including finding and excavating fossils, writing and publishing papers, reconstructing animals from fragments and more. But we’ve somehow really glossed over the role of museums that store and protect fossils and make them available for research, as well as carrying out their own work too. In order to correct this oversight, today we welcome ReBecca Hunt-Foster who is the curator on the legendary Dinosaur National Monument in Utah. Here she takes us through her background and research and the challenges of looking after one of the most famous and important dinosaur sites in the world.   Links:   ReBecca on Bluesky: @dinochick.bsky.social Here’s the link to the US National Parks website about Dinosaur National Monument: An old blogpost of Dave’s about the bitten baby Diplodocus femur: https://archosaurmusings.wordpress.com/2018/04/22/non-tyrannosaurs-biting-like-tyrannosaurs/

TIRED : asking a human expert to identify your unknown rock.

WIRED : asking AI to identify a blurry photo of your rock and then uncritically accepting the results and telling everyone you have a meteorite because Google Lens said so.

This is happening a lot lately in the meteorite and rock collecting world.

TL;DR : AI is terrible at identifying rocks, fossils, and meteorites.

Fossil clue suggests echidna ancestors lived in water like platypus
By Ellen Phiddian

A study of a 100 million-year-old bone suggests the ancient relative of the echidna and the platypus was semiaquatic — and echidnas moved back to the land from the water as they evolved.

is there direct evidence of green color preserved in any Mesozoic animal fossils? I seem to recall that as recently as 5 years ago, green was still one of the colors which had not then been found preserved in Mesozoic animal fossils, because most animal greens are partly based on cartenoids, which have much worse preservation potential.

(this question inspired by this thread: toot.lgbt/@Akki/11441503150972 )

@KateShaw has made a new episode about coelecanths. First the 1938 find of a real coelecanth and Margery Courtenay Latimer, (after whom the genus of the coelecanth, Latimeria, is named), a wonderful story.

Then she calls out a recent hoax, referencing @idoubtit 's recent coverage of the same hoax.

Finally another real coelecanth discovery, off North Maluku.

True story. While searching in the garage for a roll of teflon tape, I stumbled across a chunk of limestone loaded with fossils. (It’s a very old garage.)

Actually, this is something my son and I collected 20 years ago in St. Paul, Minnesota, where there are rich deposits of fossilized sea life at the base of the Mississippi River bluffs.

One side of a flat chunk of limestone. The most visible fossils are round segments from crinoids. There are also shells and the impressions left by shells.
The other side of the flat stone. More crinoids and a couple of very distinct small shells. And a lot of other stuff!

A new map of arthropod evolution, from #fossils to #embryos

New study sheds light on how #insects, #spiders, #crustaceans, and other #arthropods evolved their distinct body structures. By tracing these patterns back to ancient embryonic processes, the research uncovers a deep evolutionary logic behind the segmented #bodyPlans that define the world’s most diverse animal group.

EurekAlert!A new map of arthropod evolution, from fossils to embryosNew study sheds light on how insects, spiders, crustaceans, and other arthropods evolved their distinct body structures. By tracing these patterns back to ancient embryonic processes, the research uncovers a deep evolutionary logic behind the segmented body plans that define the world’s most diverse animal group. The findings challenge long-held assumptions and offer a bold new framework for understanding how developmental mechanisms shaped the evolution of arthropods over hundreds of millions of years.
