Calvert Cliffs Find - Whale or Dugong Rib (Or cool rock)


HunterMeg

Recommended Posts

Hi,

 

Looking for identification.

 

It is the first hunt in a long time, and the kids and I were searching for shark teeth along the Calvert Cliff formation in Maryland.  

 

We found what we believe is a whale rib, but wanted to get some expert eyes on it.  It is approximately 10” by 4” and 2” thick.  It is dense weighing about 2 1/2 pounds. Almost has a “metal” fell to it.  The shape just looks too unique to be a rock.  We found it near a fresh fall section.

 

What do you think it is?

Does it feel uniquely heavy in comparison to other whale material? I generally find Dugong can be quite heavy.

Yes.  It is noticeably heavier than any of the vertebrae I have found in the same area.

I agree with @NSRhunter, it looks like ironstone to me. I find so much of it at one of the sites I frequent and it tricks me into bending over to pick it up more times than not!

Thank you for the info.  The unique shape had me thinking it was bone, but it does feel more “rock” like.

I wouldn't be surprised if it had migrated that way buy now. It was north of Matoaka in 2010. :)
