Need an Identification

I found this while kayaking in the May River this morning. It has a hard calcium shell, tough (possibly hollow, no serration) spike, and what appears to be a tooth growing out of the front. The easy-to-read numbers on the ruler are in mm, so its about 2" tall, 5.5" long, and 1.5" wide.

I’ve been here most of my life and never seen anything like it.

Any clues? Anyone? I would have said egg casing, but it’s really hard. Second guess is the tail from a juvenile horseshoe crab, but the spine is round like a stiletto instead of triangular. I’m stumped!

Can you post a few more pics from different angles?

I am having trouble loading additional photos. Here is a link to a PDF that I put in in my dropbox that has four shots:

I promise there is no garbage attached to this download. The webmaster knows where to find me!

it’s part of the anal fin structure of all spadefish, the bulbous part is called a “hyperostosis”. the top-most part of the structure in your first .pdf picture shows the 2 spines that protrude to form the anterior margin of the anal fin:

Thanks! I have never seen anything like it.

yakman72 nope my wife is Ms. Chisholm. T.H.E. are just family initials. Somebody already had plain old Chisholm in the forum.

That is impressive. I thought I was full of useless info. I stand in awe!
