Hello everyone, first post in this forum! If I make any newbie mistakes please let me know and I’ll edit this post/remember for next time. I have a broken reptile tooth sifted from Big Brook (a stream near Marlboro, NJ) that dates to somewhere between the Late Campanian and Early Maastrichtian. I posted this online at another point and it was identified as a crocodile tooth from the original pictures I posted. I’ve been sitting on this one for a while though and it doesn’t seem to line up with the teeth from other known crocodilians and from this area (Brachychampsa, Borealosuchus, Hyposaurus, etc). Can anyone offer a second opinion? It has really prominent anterior ridge on the front of the tooth which makes me think it’s possible a theropod but it doesn’t look like Dryptosaurus. The back half is broken which means I don’t have any serrations to use as an ID. I’ve included the files in this post. I have also included some bonuses to these image though. I believe I found what appears to be a bird femur in the brook but I’m not certain if this is a quaternary find or actually from the same formation as this tooth. Anyone have a family id or insight on how to check if this is fossilized or just turned black from the soil? I also included some images of saurornitholestine teeth which I personally thought are close in appearance to this tooth. Thinking I might be too hopeful on that ID but thought it was worth sharing my thoughts lol. Material of these dinosaurs has been found in New Jersey!

Taking my son for a nature hike yesterday morning, trying to inspire a love for the outdoors onto him. We ID everything we find, but this is our first fossil! Found this deep in the woods in millstone, Monmouth county. Spoke to two paleontologists, one said pycnodonte and the other said Ostrea. Help! I don’t know anything about fossils.

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?

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.

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.

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.

This was found in the spoils from dredging the C&D Canal in the 1980s. Recent removal of spoils sand for road construction in the area exposed previously- inaccessible layers of sand. Formerly known as Ostrea panda. It remains in the same Order. This species is not listed in the Delaware Geological Survey's bulletin about the fossils of the Canal. It is distinguished by its round shape. Pycnodontes are an extinct genus of oysters known as foam or honeycomb oysters.
