This Devil Ray tooth, Plinthicus stenodon is a common found in some Pungo River sediments. It is also found in the Pliocene Yorktown, but is much less common there. Most found are damaged in some way. Being undamaged makes this specimen special.

This tiny sevengill shark tooth is the smallest I have ever found. At 8mm as a lower tooth it must have been a juvenile or even new born shark.

Lee Creek Cetorhinus (Basking Shark) teeth are extremely rare. While the Oligocene specimens and some Miocene locations have been assigned to C. parvus and the later (Pliocene-extant) have been assigned to C. maximus; the Lee Creek teeth have not been assigned to species level. The west coast species from the middle Miocene Sharktooth Hill Bonebeds have been assigned as a new species C. huddlestoni (Welton, 2014); and is a very common tooth there.

This is just a small piece/edge of a layer that must have encompassed acres. It was a horizontal layer extending into the base of a 50 foot vertical cliff, and so, very difficult for me to recover even this small plate this is a type of sardine---Xyne grex- 1 comment

The hiway department cut a road through this 5 ft thick sandstone zone, and pushed the talus over into the adjacent canyon. Most people collect along the road cut for other types of fossils. One day I decided to explore the area, and climbed down into the steep canyon full of the rubble from above. that was FULL of ticks, poison oak, and a very steep unstable slope, --- making it very difficult to pack out good material.( prob why people didn't enter this area), where I found and recovered many of these unusual echinoids. Since no one had collected this lower area, I found soo many of these specimens(dozens), many large multiple plates, I had to leave many down there vowing to soon return to gather the rest and explore more. Due to the extreme difficulty I haven't returned since. (over 45yrs)

Front view of an unidentified vertebrae that is nearly 4.5 inches long and 2 inches wide. This vertebrae is to large for a dolphin and still has the cookie formation in the middle indicating the specimen was a juvenile. -

I believe this is a form of coral but am not certain. I've recovered a few of these and the color is rust, but that's due to the absorption of the brackish water in the bay. -

Fragment of a juvenile C. Megalodon. These are rare at Calvert Cliffs but certainly are out there. I have recovered a few fragments, but so far no completes.-

This is what I believe to be a Mako shark tooth. These aren't as common at the Calvert Cliffs area as tiger shark teeth and this is one of the nicer specimens I have recovered. -

Left side is a Hempristis serra and the right side is what I believe to be the tip of a crab claw. -
