I found this on the slope of Forked River Mountain last nite. I had walked there from Lacey Road. Very cool. The rains uncovered it. I think it is from a group of marine animals called Echinoderm. Or maybe from the Order Actiniaria...maybe a sea anemone?

A place I used to work had their property covered in stone and you could find these in every square foot. I have a small collection of them. How old do you think they are?

I wish I knew. Lets consider though, that NJ was covered with seawater many times. And, I have heard that the FRMs were formed because of the great rivers that flowed through NJ on the way to the sea, and that the mountain was just a gravel sand bar. I want to say......greater than 20,000 years ago.

Good find, Bob. Might it be some kind of coral, perhaps Rugosa?

In any case, I think we're looking at a fossil that represent a species of marine animal that went extinct around 250 million years ago. Perhaps SpungMan can shed some light on this.

Coral did cross my mind, but I was looking at the aristotle's lantern of the urchins and see a resemblance. I don't think coral have that kind of thing.
