belemnite battlefield?


Recommended Posts

Funny story with this one, these are from a hunt from about a year ago. I put my bag in the washer and when taking it out this fell out. 

Lucky it survived after a wash.

These are very small ones if they are belemnites.

Not exactly a battlefield.

Belemnites are thought to have undergone mass die offs at spawning. 

These could easily be echinoid spines though.

If that's from the Yorkshire coast it's probably a Carboniferous erratic.

I've found a few like it and I think they're hexactinellid sponge root tuft spicules (search Hyalostelia although that's just one genus defined by its main body spicules - the name is loosely used as a form genus for the roots).  

Another possibility is productid brachiopod spines though you'd expect some shells as well.

 

90% for sponge root tuft. :) - this area has the usual parallel structure before being broken up:

So not belemnites? 

I found this at either runswick bay or Mappleton, probably Mappleton.

Definitely not belemnites. :) Both locations are good for Carb erratics.

 

Your second photo shows it's packed with Carboniferous crinoid fragments - two large bits here, at top and bottom:
