A mischievous archaeopteryx has appeared!

Megacerops was a large ungulate from the White River Formation (38-33 million years ago) of the Midwest in the US. They resembled Rhinoceros, but had bony nasal horns that were covered by skin, not a keratin horn!

Here are some of the fossil finds from this year’s dig season: the crown jewel being a Tyrannosaurid tooth. Also shown are a Metasequoia cone, a fossil tendon, a crocodilian tooth, and some freshwater ray crushing teeth, plus some amber!

My first big bird project is done! I’m excited to show you all this bird that took me so long - at least a few months! This guy comes from the green river formation and is the most common bird found there: Primobucco mcgrewi.

Here are the answers to today’s #findthefossil! Some of the suspicious looking bits are actually dead sagebrush leaves. Included in the mix here are turtle bits, various dinosaur chunks, and maybe some crocodilian bone pieces. I’ll try to post some more of these challenges in the future!

Here’s a game for y’all!
I have a picture with fossils in a “float” deposit, where they’ve been washed out of the rock and precipitated out in the ground in the hell creek formation! Let’s see how many you can spot! I’ll post the answer in a little bit! Instead of #findthatlizard , #findthatfossil !

It’s time for: a creature spotlight!
On the ranch where the crew and I dig every year, there are harvester ants that gather and sort small sediment for their hills! They are known to grab small microfossils (like teeth) and small bits for their hills, including bones!

I’m alive!! I had the wildest field session this year, including a brush with a wildfire and some cool wildlife! Stay tuned for photos of the stuff I found on my dinosaur dig this year!

Gonna be cleaning some scraggly T. rex bits to sell in my shop at some point. Keep an eye out! Hopefully I can get them listed before I head out on this year’s trip! Unfortunately, these bits aren’t worth salvaging as an entire specimen due to how much weathering had been done to it.

A micro texture on a placoderm fish from presumably the red hill deposits in PA. So cool to see these up close!

A second bird! Likely a larger waterfowl like presbyornis. Sources from the green river formation.

A pachyceohalosaurus I drew while at #paleofest!
It was a blast meeting and seeing so many people I look up to!
This guy is based off the skull model in the Burpee Museum in Jane the Juvenile Rex room!

Steamed owlette anyone?
(In all seriousness, I didn’t get the steam up under this gorgeous eastern screech owl. I’ve been correcting the pinnate feathers on this guy)

It’s time to groom and tidy up a hawk! This guy had paint on his tail feathers! Hopefully a good swabbing and a small amount of steam will help him look like new.

Little late for #fossilfriday, but here’s a finished Messelornis leg from the green river formation!
The guy who worked on this previously did me no favors by breaking the femur and tendon remains, hence the bedraggled appearance.

My first bird piece isn’t exciting to look at, but it’s probably an arm bone overlying where the flight muscles attached, known as the keel, on the chest. Approx. 50 million years old from the green river formation! #fossilfriday #museum
