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.
🐢 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
