San Juan Basin Paleontology Project is a basin‑wide research initiative integrating fieldwork, fossil documentation, stratigraphy, and public outreach across the Late Cretaceous formations of the region and beyond.
🛡️ New microCT scans are giving us our first look inside the armor of the nodosaur Invictarx zephyri! These heavily armored, plant eating dinosaurs roamed the San Juan Basin (and elsewhere in North America) during the Cretaceous.

🐢 Memorable moment from our recent field season from a terrestrial locality in the Menefee Formation, another Campanian unit in the San Juan Basin. One of the highlights of the summer was the discovery of a remarkably complete baenid turtle shell preserved in a hard sandstone ledge

🦈Highlights from our recent SJB field season this past summer, including explorations of our marine Cliff House "Hills Have Eyes" locality, practically exploding w/marine vertebrates, including chondrichthyans (cartilaginous fishes), actinopterygians (ray-finned fishes) & a few mosasaur specimens

We evaluated the Coniacian-Santonian turtle fauna of the Crevasse Canyon Formation (New Mexico), including evidence for one of the earliest known plastomenid turtles and a reassessment of the baenid turtle "Neurankylus notos"

Introducing the San Juan Basin Paleontology Project, a basin‑wide effort to document Late Cretaceous fossils, stratigraphy & landscapes across one of the most complex regions of the Southwest. We’re launching field surveys, specimen work & geological mapping to clarify Cretaceous life & environments
