Northern Nj Fossil Id

Recommended Posts

prhomme

I was out hiking in Kinnelon over the weekend along a ridge (1000 vertical feet) and came across a large rock with fossil shells in it. Am hoping someone can help me ID them, since I don't know anything about fossils! There seems to be several different kinds of shells here. Some of the shells are ridged (large impression all the way to the left of the photo) and some are smooth (top of photo) except for a large ridge in the center. There is also a circular shaped fossil (center of the photo) with a hole in the center and "knobs" around the outside of the shell, in addition to some things that look like pecan shells (2 of them at right and top of photo). I broke a piece of the larger rock, which is about 4 inches by 4 inches (attached photo). Thanks in advance!

There appears to be a thin finger of Devonian aged rocks in that general area, Based on THIS MAP. (Blue streaks)

But there may also be some Ordovician and Silurian?

Looks like some internal molds and a cast or two of a few different types of Brachiopod.

I'm not real good with brach ID's, but the ones in the upper right of the photo may be some type of Spiriferid brachiopod.

Hopefully Shamalama, Fossill Dawg or some other invert expert will weigh in and help.

Regards,

"Large rock" may have been a glacial erratic, so almost any age would be possilbe. Looks brachiopodish to me too. Wonder what the invert experts say :eat popcorn:

definatly internal molds of brachiopods. now which brachiopods will be the hard part. More views of them will be needed.
