Setting up a small study involving paleobotany. It should be a bit of fun even if it is out of my comfort zone.

It is unfortunately.
He got mad that they didn't remove him from the impeachment exhibit (they stressed that they were only reorganizing the exhibit)

Braincase and digital endocast of a loricatan pseudosuchian (Reptilia: Archosauria) from the Upper Triassic of Nova Scotia (Canada) - PalZ We present a detailed description of an incomplete but excellently preserved braincase and a digitally generated endocast of a pseudosuchian archosaur from the Upper Triassic (Carnian) Evangeline Memb...

Phytosaur fossils from across 3 states.

1: Arizona
2: Texas (harder to find)
3: New Mexico

This is the metatarsal of a phytosaur based on the thickness, definition of the collateral ligament pits on the distal end, and the slight curvature.
The curvature and length possibly point to this being from digits III or IV which are the longer digits and built for weight-bearing stresses.

Pretty nice, partial, phytosaur squamosal!
The smooth part of the fossil (in the top right image) would have been where it connected to the orbit!
The squamosal on the right and left side of the skull would have also helped to form the supratemporal fenestra!

Amazingly well preserved phytosaur coracoid base.
Definitely from a large specimen!

"If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then we're up for grabs for the next charlatan, political or religious, who comes ambling along." - Carl Sagan

Scapulocoracoid fossil from the redonda formation of New Mexico.
Possibly an adult Redondasaurus

Sub-adult Machaeroprosopus femur

Phytosaur partial femur
This femur was crushed at some point in the distant past, and, through lithification, the broken pieces were "glued" back together!

Alligator Mississippiensis fossils from the Pleistocene of Florida!

Joined the Dallas Paleontology Society on their trip to the Martin Marietta Quarry.
Found some decent sharks teeth from a few different species and several good sized nuggets of pyrite!
I definitely recommend anyone with an interest in paleontology to support and join!

Taphonomic signatures of a new Upper Triassic phytosaur (Diapsida, Archosauria) bonebed from India: aggregation of a juvenile-dominated paleocommunity A monotaxic bonebed containing numerous phytosaur specimens is reported from the Upper Triassic Tiki Formation of India. The comprehensive minimum number of individuals is estimated to be 21, which...

An older paper from 2019, but one of the only known instances of phytosaur parental care. The site also appeared to show young living in cohorts.

More phytosaur fossils. Again, from a part of the chinle formation in Arizona!

Phytosaur rib, likely cervical, found on a private ranch in the painted desert area of Arizona, a part of the Chinle formation.

The fact that phytosaurs have no modern relatives and the fact that their behaviors and procreation are still mysterious has helped drive my hypothesis that phytosaurs may have given birth to groups of live young. A hypothesis I hope to prove fully or falsify one day with new finds!

Still my favorite phytosaur fossil to look over!
