This appears to be a very large ammonite (3-4 feet in diameter) in the side of a gully wall. Quicksand (wet chalk) 10 feet below and the ledge is 10 feet above, so this will prove to be a challenge to excavate.
A better view of the Clidastes mosasaur jaw found by Claire.
Larry found a handful of very detailed fossil shark coprolite.
Fossil fish jaw (Saurodon) found by James Lamb as he was blazing a trail to a new collecting location.
A nice string of connected fish vertebra, possibly ichthyodectid, also found by Claire (who'd you expect??)
