Stumped on the NJ sea rolled find

[jerseygurl]

I found this during a low tide walk earlier this week on the bay. I usually find lots of fossil fragments, and sometimes if the sea chooses to be kind to me, I get to take home a top pocket find fossil. On this particular day I did find a complete gastropod mold in addition to this mystery. I’d be interested to hear thoughts on this. In I can’t find anything like it online or in any of my books.

Looks like sea tumbled fossil bone.

Yup, Chiplodocus methinks.

I’ll add it to the chip jar. I probably have halfasaurus by now.

To date, I have over 65 fragments, fossil reptile bone-like pieces.  Some are so worn, I can't tell if they are truly bone or coral.  This specimen is unlike any that I have found, and it looks a lot like a root to me based online & print research.  I have never been so lucky and so I highly doubt it.
