Pathological belemnite???

[DatFossilBoy]

Hey!

Picked up this really interesting belemnite 1 month ago when I was in Lyme Regis, England.

It is very weirdly curved, I was wondering if it could be pathological. (Don’t even know if it’s possible).

Maybe just a rare fossilization??? What do you think?

Ps: it broke naturally so I had to repair it with glue (black line)

Yes, this is an awesome pathological belemnite. I saw this pathology a few times already, but they don't appear to be common. A very nice piece.

"A Late Cretaceous pathological belemnite rostrum with evidence of infection by an endoparasite"?

Quoting Hoffman/Ansorge(Neues Jb,etc),just out.

Paywalled,alas

Nice specimen and quite rare. There's possibly some diagenetic deformation as it has slight matrix filled fractures (that happens in some beds) but it's quite convincing.

 

Here's a classic that W. D. Lang collected from there (now in the Natural History Museum) - photo from the Palaeontological Association Dorset Coast guide.

 

 

 

And a Yorkshire Acrocoelites of mine which I sectioned to show when it started to grow sideways - :

Awesome pix, Tarq. Really.

Love reading about pathologies in fossil molluscs ever since Hengsbach did his monumental series in Senckenbergiana Lethaea on ammo pathologies. 

edit:look at fig 4 a& b(or don't,"Bad pix pdf"):

Thanks, Ben - I know and love those figures. Is that the Duval-Jouve (1842) original source (which I haven't seen)? Fig. 4 is amazing.

 

You can see the growth lines in this version from Naef, Die Fossilen Tintenfische (English version) (with a couple different):

Great find. 

Very interesting thread too. 

I'm going upstairs to check all my belemnites now.

That's Hengsbach using Duval-Jouve's figures,yes.
