"Feelin' Groovy" today! I'm a self-taught and well-mentored paleontologist. I've been volunteering at my local natural history museum, identifying, cataloguing, and studying a donation of thousands of cretaceous invertebrates from a single locality along the Chesapeake and Delaware Canal in the US. My first paper, peer reviewed, is now online. https://zenodo.org/record/7901663#.ZFk6xnbMJPY- 18 replies

I had heard that C and D canal site had new dumps. I had heard that the C and D site was going to be covered over, I had heard that it was removed/recycled. I went out last week to look. There are fewer dunes, and evidence of tractors and trucks, however there is still plenty of unchanged of material. It remains a harvest of belemnites and very little else.

Scapanorhyncus texanus (Roemer, 1852) From the Late Cretaceous spoils of the Chesapeake and Delaware Canal, Reedy Point, Delaware Microfossil - 7.6 mm Not the best example of a shark tooth, but a rare find for Reedy Point. Most shark teeth were found further west.-

This is a very rare find at this site. Although two members of the genus have been reported along the C and D Canal, this is the only one I've found at Reedy Point in 17 years of collecting there! PLEASE NOTE: It is possible that this was carried there during frequent human activity - perhaps in a tire tread from a vehicle that came from another site along the canal. This specimen has a 4mm pearl bud near the hinge on the interior side of the valve. Because there are more than one species of Pteria at the canal and this shell is heavily worn, I am refraining from narrowing it down to a species. Of the two reported, only one really resembles it. P. petrosa (Conrad) has strong, concentric growth rings, but no costae. P. laripes (Morton) has strong costae and fine growth lines, so is probably a match.

Vertebrae from either a stingray or skate. Found in close proximity to each other at a site where such things are rare, so probably from the same animal. L:arger one is about 3cm wide. Found at Reedy Point, C and D Canal, Delaware. Maastrichtian. -

Two Exogyra cancellata shells from the Cretaceous spoils of Reedy Point, Delaware. Although Exogyras typically detached themselves from their anchorage while still very small - about 2-3 cm - these two animals continued to live and grow together. The lower valve is about 10 cm on the long axis. -
This one is bugging me!!!! I know this is a brachiopod. I found it at the Reedy Point spoils along the C and D Canal in Delaware. It is 1cm in diameter. I have found two of them in the sand but none of them in the books. I have looked in Weller 1907, Wade 1926, Stephenson 1923, Richards 1958 and 64, and Lauginger 1988. I asked the folks at the repository for the Monmouth Amateur Paleontological Society. No dice. Look familiar to anyone?

This specimen comes from the 1980 dredge spoils of the C and D Canal. The type specimen for this species comes from the Navesink Formation exposure of the same canal, not far away. Known by locals, it was not actually described until 1986. Although not the most common of species at this locality, and almost unknown outside of Delaware, these miniscule urchins were nonetheless plentiful at the Reedy Point spoils. Recent excavation for barrow removed most of the sand where my specimen was found.

Vertebrate material of any kind is extremely rare at this locality. However, this is the most common vertebrate represented at Reedy Point. Found while sifting through micro matrix collected from an especially prolific, recently exposed spot that will soon be removed by bulldozers.

As battered as this is, it is an unusually well-preserved specimen for this locality. Although there are brachiopods and bivalves that preserved as calcium carbonate at this locatlity, most gastropods in the Cretaceous of Delaware are either steinkerns or are preserved as battered phosphate with phosphate in-fill. Gouging appears to have occurred after fossilization since the matrix does not completely fill the gouges. Most shell predation at Reedy Point came from clionia sponges and boring clams. This resembles neither. This was found in loose sand from dredge spoils.

Glycymeris clams have ridges along the inside edge of the valves that extend past the cardinal area. Internal molds tend to include these teeth, making them very distinctive. As of the time this was posted, this was the only member of the genus listed in the Paleobio Database for the Cretaceous period and it is only listed as being found in NJ. However, Stuart Weller (1907) and Horace G Richards (1958) not only include them in the C and D Canal zone, but identify three different species for the region. This one is the most common and the only one THEY found outside of NJ. This is most likely from the Mount Laurel formation. It was found among the Mount Laurel index fossils. However, Navesink Formation fossils are also found in pockets in this spoils area, so the possibility that this came from the Navesink and got mixed up with the Mount Laurel material from constant human activity cannot be ruled out.

So sweet! This is a very rare Cretaceous echinoid (sea urchin), Boletechinus. They are typically no more than a couple mm in diameter. This one is shown next to a pencil eraser. Most of the ones in the Smithsonian's collection come from sand and silt removed for the creation and maintenance of a canal, which exposed fossils well below the surface. This one comes from New Castle County, Delaware. -
