Work in progress on a goniatite painting. What other critters should I add?

A partial Cretaceous coelacanth jaw of an Axelrodichthys lavocati from the Kem Kem Group in Hassi Zguilma, Morocco. This species of mawsoniid coelacanthiform was formally, and may still be, assigned to the genus Mawsonia. These giant lobe-finned fish were likely a vital food source for the larger piscivorous predators in the deposit such as Spinosaurus, Sigilmassasaurus, and Elosuchus.

Happy Fossil Friday! This is the skull of Liberty the Lambeosaurus from the upper Judith River formation near Havre, Montana. It was found by Jack Wilson and Denver Fowler in 2020 and its preparation is nearing completion in our lab.

Fossil Friday: The Horned Tyrannosaur

Today we will be talking about the horned tyrannosaur from Late Cretaceous Alberta and Montana better known as Gorgosaurus, the "dreadful lizard".

Gorgosaurus got up to 30 ft in length, just a little bit smaller than the contemporaneous Daspletosaurus. It was first discovered in 1913 by Charles M. Sternberg and described by Lawrence Lambe in 1914.

It can be found in the Dinosaur Park, Judith River and Two Medicine Formations.

It's lacrimal crest was a bit more pronounced than other tyrannosaurs giving it the nickname the "horned tyrannosaur".

Gorgosaurus spent almost half it's life n the juvenile stage before hitting a growth spurt that got it to adult size and shape.

Many pathologies have been found on Gorgosaurus bones. It seems that they had a knack for injuring their fibulas. Like other tyrannosaurs, many specimens have evidence of intraspecific face biting.

I hope you have enjoyed learning a little more about tyrannosaurs and tune in tomorrow for the first bracket of March Madness! Fossilize you later!

It's Fossil Friday🦴, be like Carnotaurus sastrei: Run like the wind! 🦖

I have started volunteering at a local nature center. They have this very cool piece petrified wood in their collection.

For this Fossil Friday i fished already dry of some other specimen from my collection.

Probably some Gryphea arcuata - oisters shells.

Ask to all : Brachiopod shell fossils or are these nautiloide shell rock Fossils?

New fossil additions.

I like to share for this little Fossil Friday, some pics of the newer fossils I brought from the lasts flea markets in the previous weekends.

The chalk rock corals were found or excavated collected from the Gosenkreide area from Austria.

White chalk like limestone with those nicely prevented pattern of the former polyps and corals skeleton here to seen.

Also along an new trilobite, and an ammonite nodule half in it’s rock matrix.

Here's my 2022 Nature cover featuring Tupandactylus. This painting was commissioned by Cincotta et al for their paper describing multiple feathers and their colours from a pterosaur fossil! This implies the common ancestor of pterosaurs and dinosaurs might have had feathers. Fascinating!

A dinosaur tooth of a Marshosaurus bicentesimus from the Brushy Basin Member, Morrison Formation in Dinosaur, Moffat County, Colorado, United States. Marshosaurus is a lesser known megalosauroid or piatnitzkysaurid of the Upper Jurassic often overshadowed by its famous contemporaries like Torvosaurus, Allosaurus, and Ceratosaurus. The blade-like teeth of these obscure theropods can be distinguished from the similar morphology of Allosaurus by its finer serration density and a DSDI greater than 1.15. These teeth have a similar condition to those of megalosaurids in which the mesial carinae does not extend to the base and stop around 2/3rds the way down.

For Fossil Friday, some slightly abstract photography with a slice of fossil bone. A bone from what? No idea. I've had it since I was a kid and bought it with my allowance. It was labelled... fossil bone.

Considering that I was in Drumheller at the time, it's probably some sort of dinosaur.

Yep, that narrows it down.
