The long pointy tooth is an Enchodus tooth, and the others are shark teeth
This month's trip was to northern Mississippi, where we collected in the Coon Creek formation. The area was once a bay in the Gulf of Mexico. This is a Late Cretaceous site, where we found numerous turritella (most in an extremely fragile condition), and even more crab and lobster parts, mostly looking like they had exploded, though several intact "bellies" and a couple of claws were found. The finds of the day had to be the mosasaur tooth found by Don H., and the fragment of a duck-billed dinosaur (hadrosaur) tooth found by David. This site is being studied by George Phillips, paleontologist at the Mississippi Museum of Natural Science, who will be reviewing our finds for anything of scientific interest. The hadrosaur tooth fragment has already been sent to him for inclusion in his research.
Don C. had this to say about his collecting efforts for the day: "I'm very happy with my haul of crabs and shrimp (7 different genera and species in all), plus I got quite a few gastropods and bivalves, a squashed nautilus, a good piece of an ammonite with sutures, an Enchodus fang, and a small shark tooth. I brought home a bag of clay to sift and I'm still finding all manner of micro goodies too."
The diehards of the group had an evening of BBQ at a local restaurant, and as everyone headed home, two additional sites were scouted, neither of which appeared promising.
