T. rex for #FossilFriday!

I'll miss this display of Trinity at the Sauriermuseum Aathal

Did you know that you can find fossil dinosaur eggs in Alberta? In 1987 Wendy Sloboda, then a teenager, was scrambling around Devil's Coulee near Warner, Alberta when she came across the shells of what would later turn our to be eggs from a species of hadrosaur. There's now a wonderful museum, the Devil's Coulee Dinosaur Museum, which displays finds from the area and provides tours.

#FossilFriday Any day is a good day for trilobites. Here is Zlichovaspis from the Late Devonian of Morocco. Beautiful animal. #paleontology

This weeks #Lego #FossilFriday is #Utahraptor

In 1975, Jim Jensen found fragmentary remains near Dalton Wells Quarry, Utah.

In 1991, Jim Kirkland, Robert Gaston and Donald Burge uncovered even more remains.

In 1993, Jim Kirkland named the species Utahraptor ostrommaysi after the state it was found in, and John Ostrum, who investigated Deinonychus and its relationship to birds, and Chris Mays who helped research Utahraptor.

New review, just in time for your Easter #FossilFriday: Palaeontologist Gregory Paul updates his field guide to dinosaurs again, ensuring it remains the largest and most up-to-date collection of skeletal diagrams in print.

Happy #FossilFriday - check out the beautiful fangs and leg bases of a ~409 million year old trigonotarbid arachnid from a paper by Emma Long and colleagues at the Natural History Museum, London. These are 3D reconstructions from laser microscopy data (schematic shown right)

Happy #Minnestoa #FossilFriday These bison remains are part of a bone bed discovered east of Melrose, MN in April 1967 by Ivan Brouwer, a dragline operator working near a creek along Interstate 94, Ivan shared some of the bones with his friend Robert Freeman Sr. Rumor has it that Robert Sr. and his son planned to reconstruct a full skeleton from these bones.

The existence and whereabouts of this skeleton remain under investigation today!

Happy #FossilFriday, check out these Lissodus teeth from the Substation Quarry! An array of blunt teeth would have helped these little sharks crush up crunchy crustaceans as they swam through a grand, ancient lake. These teeth almost certainly represent a new species! (1/2)

#FossilFriday The pterosaur Muzquizopteryx at the Museo del Desierto in Saltillo

Palaeontologists Darren Withers @outfossiling (left) and Richard Forrest @richardforrest (right) visited us to see the ichthyosaur they donated now on display, and also to present some more bits of it to the museum! Bones from the skeleton continue to be discovered from the dig site. We'll add these to the display soon!

A 30,000-Year-Old Feather Is a First-of-Its-Kind Fossil - Eos #FossilFriday #paleontology #geology

This was the day I learned that plant impressions are surprisingly hard to photograph.
#FossilFriday

Some fossils are very difficult to collect from fissile shales. So I take my macro photography camera with me at all times, especially to capture the moment of a fresh shale split. One perfect photo opportunity was when my friend discovered this small delicate well preserved teleost fish preoperculum ( pictured ) A small, movable bone located in front of the operculum (gill cover) in fish. It's a crucial part of the gill structure and plays a role in both breathing and feeding. #FossilFriday

April 18, 1788, birthday of fossil-collector & artist Charlotte Hugonin Murchison, wife of Roderick Impey. She introduced him to the world of geology & later edited and illustrated his books.

The "Ammonites Murchisonae" (now Ludwigia murchisonae) is named after her #FossilFriday

The Laetoli footprints are more than ancient impressions—they’re a glimpse of movement, of presence, of connection. Someone walked across volcanic ash 3.6 million years ago. And left us a story. #Laetoli #FossilFriday #HumanOrigins #WOPA #PaleoPost
