That’s a wrap on two weeks of fieldwork at Petrified Forest! A few fossil highlights, in order: azendohsaur tibia, shuvosaurid femur, shuvosaurid pubic boot, and a fragment of a temnospondyl interclavicle

New @JVP_vertpaleo study reveals a "peculiar" ancient croc that began life on four legs before learning to walk on two🐊

This 25-inch tall reptile looked just like the ornithomimid dinos it lived beside in the Late Triassic - but it evolved separately.

It's @SVP_vertpaleo #MemoirMonday, where friends of the Permian get to check out 257 pages of new information on the tetrapod fossil records of Tanzania and Zambia.

@reptiliferous Congratulations Dr. Jenkins! 🎉

[Megan Whitney @_megwhit_]

Big sky WY fossils got to check out the Windy City big sky. @CAS_Loyola students did some rooftop screen washing of micro vertebrate fossils and sorting team recovered two beautiful mammal teeth this morning. Fun #FossilFriday in the Whitney Lab!

This is our 10th field season @PetrifiedNPS, but today is my last day. The Kaye Quarry is still producing many bones per day, including this near-vertical limb bone. @burkemuseum @UWPaleo

[Elliott Armour Smith @EAS_paleo]

Thanks for celebrating 10 productive and rewarding years with us! @burkemuseum @PetrifiedNPS

[Adam Marsh @NotThatMarsh]

Hanging in the @burkemuseum shuvosaurid quarry at @PetrifiedNPS with @KelsieAbrams3 and @EAS_paleo et al., missing @ChristianSidor as he flies to Africa. Here is a femur, tibia, pubis, rib, vertebra, and a few mysteries. #FossilFriday

[Christian A. Sidor @ChristianSidor]

Finally got a chance to visit @museumofnaz today. Check out this Desmatosuchus shoulder spike from the Chinle Fm of AZ.

Let the games begin!

In early May I collected what I thought was a small dinosaur femur in the Devil’s Playground at @PetrifiedNPS.

Oops! After I prepped it it turned out to be a shuvosaurid. Foiled again by these cool bipedal pseudosuchians.

[The Anatomical Record @AnatRecord]

Riojasuchus tenuisceps, a Late Triassic pseudosuchian, had unique traits sparking debates on its locomotion. Using a new 3D model, findings suggest an erect posture but reveal mixed evidence on its locomotor function.

Wrapped up a super productive week in the Lance Formation with a collaborative group from @CAS_Loyola and @IMNH208 . Thanks to the whole team but a special thanks to our hosts @TomKaye_ and Carol Kaye.
