·Big Brook, NJ, USA

·Panned fr brook bottom w marl+

·Miocene form. overlaps Late Cretaceous?

.Attach: images of 2 fossils

.(found pre-2020)

 

I assume these (3+1) fossils may be from the "same" species, two diff. animals? No outstanding horizontal/diagonal "veins" from the prominent central ridges. Rookie request to ID b4 summer trip to c Dr. Parris, NJ St. Museum, Trenton. Thx

These look like some of the ironstone/bog iron concretions from the area, to me.

The third photo down does resemble a worn out Ceratopsid tooth. I suspect it is a coincidence though.

Dinosaurs were extinct long before the Miocene came around.

Thanks Rockwood

 The larger images.....could they not be from a Hadrosaur-tooth?

As you know, at Big Brook iron infiltrates/encased "everything"! Could the larger images not be a very worn Hadrosaur tooth? Or would we should we have more root? In other words, this artifact is just too thin? Thx

Although this has some resemblance to a Ceratopsian tooth, not hadro its a Concretion.

 

 

Need additional views to comment on this specimen, initially looks geologic
