My first fossil

[HaleScar]

Hi everyone! I'm new here and I found this in a freshly tilled cornfield in Northampton, Pennsylvania a few days ago. I have no experience, but am very excited to get some info on this and maybe start hunting and get a collection. Any idea of what the shells are or the approximate age? Thanks for any info!

A few more pictures detailing all sides of the piece would be appreciated, but it looks like you have some brachiopods (or possibly bivalve?) from the Cambrian or Ordovician!

Welcome to the Forum.   

I agree these are likely brachiopod or pelecypod  imprints. 

They are very worn, however so accurate ID may not really be possible. 

I would say they are more likely to be Ordovician in age.  485-443 mya.

Looks like some sort of Ordovician Pectinoida species. From your specific location in Pennsylvania, it should be around 500 - 430 million years old. (some parts are slightly older and in late Cambrian)

they are old because where you are located. Here is a map of pensylvania showing the map and which age fossil can be found where

Probably orthids, in my opinion, but I just like guessing.

Just amazing! I would've never guessed I'd be holding something like this in my hands. For all I know they're a dime a dozen, but I think it's awesome! Thanks again for all your help!

Keep looking. You'll find more. 

But one never forgets the first time.
