Me doing field paleo with that student who needs 10 reminders a day about drinking enough water and then tells me they forgot both their water bottles in their tent.

My dude, you gotta work with me here! 😩

This is the first fossil I ever saw in the field!

Love Pachyrhizodus! Excavated one back in 2018 with one of my high school field programs. We're finally on the docket to get it prepped out this summer!
Initial fossil exposure being photographed with scale+grid system. Pachyrhizodus skull is protruding out of hill slope. Body and tail are running back into the hill. Working on excavating around the Pachyrhizodus specimen. The skull has been capped with a plaster jacket to protect it while we work. Extensive excavation around the full Pachyrhizodus specimen. A robust plaster jacket including wood reinforcements have been added. Undercutting the jacketed specimen is nearly finished. We ended up using a concrete saw to cut the specimen in half to make it easier to transport back to the Sternberg Museum. Pachyrhizodus in the truck! Ready for transport back to the Sternberg.
