Not often fossil plants get reconstructions but part of the new New Mexico Musuem of Natural History and Science exhibit on the early Paleocene San Juan Basin has reconstructed early Paleocene sycamore leaves based on specimens from my dissertation! #FossilFriday #Paleobotany
Reconstructions of early Paleocene scyamore leaves from northwest New Mexico showing a large terminal and two small lateral leaflets of the plant.Reconstructed early Paleocene sycamore tree and early primate at the New Mexico Musuem of Nature and Science. Small brown mammal resting on a limb of a white and grey tree with silk leaves.

Diversification of angiosperm reproductive strategies predated the end-Cretaceous extinction
Angiosperm reproductive evolution is traditionally linked to the end-Cretaceous biotic crisis and subsequent ecological restructuring. Here, we report diverse and unexpectedly large diaspores (dispers...

Spent the last few days collecting a latest Cretaceous (latest Maastrichtian) flora from the Naashoibito Member in the San Juan Basin of northwestern New Mexico. First time I’ve ever found any within the Naashoibito!

Found some latest Cretaceous dinosaurs from the Naashoibito Member of northwestern New Mexico today while doing some pre-field season reconnaissance today. Hopefully this bodes well for our work later this month!

Tip for students contacting potential advisors about graduate school in paleontology - probably not a great idea to tell me that you'd rather do dinosaurs but my "boring" plant fossils are ok I guess and that you probably wouldn't get bored or uninterested in your first email to me.

What do we know about the last surviving dinosaurs, living right before the asteroid? And is Nanotyrannus a tiny tyrannosaur species or juvenile T. rex? Lindsay Zanno & I talk through the big questions with Ira Flatow on today's @scifri.bsky.social ! www.sciencefriday.com/segments/din...

Were Dinos On Their Way Out Before The Asteroid Hit? Maybe Not
Two new studies suggest that, contrary to longstanding beliefs, dinosaurs were not on the decline before the Chicxulub asteroid impact.

New dates on fossils from New Mexico reveal a community of dinosaurs that were thriving right before the asteroid strike, including 80-foot-long, 30-ton giants like Alamosaurus. I’ll tell you more in my latest for NatGeo. 🧪

New evidence reveals dinosaurs were thriving right up to the moment the asteroid hit
Newly dated fossils from New Mexico challenge the idea that dinosaurs were in decline—and suggest instead they had formed flourishing communities.

Our new paper is out in @science.org #ScienceResearch Our understanding of the dinosaurs at the very end of the Cretaceous is limited by few localities. What dinosaur biogeographic patterns were present leading up the K/Pg boundary? What can these tell us about end Cretaceous dinosaur communities
