Lobster tail style fossil ?


Crann

Recommended Posts

Out hunting this morning, opened up a slab of shale and this was inside, looks like a lobsters tail to me but could be anything in this game, found on Yorkshire coast, thanks.

Looks a bit more like a bivalve, to me. :headscratch::unsure:

With squish out ?

That, or an encrusting bryozoan? :headscratch:

It also had a "tail" that broke up when it became loose from the shale, wish I got a photo of it beforehand... grrrrr

Any info on how guards preserve in the shale ?

Picked it up and it is falling apart now, the joys of the unknown...

I'm pretty sure from that that it is a phragmocone.

They preserve well. This sort of thing (from the Grey Shales, Lower Toarcian Stage) - the phragmocones are often much less well preserved than this and can be grey instead of reddish but some of the Upper Lias beds are noted for them.

I've a few lobsters and none look like that. I'm sure it's not a lobster. 

This matches the tail that was there before it fell to pieces, you think possible ?

From your last photo of the specimen, this is typical preservation of phragmocones for the area.

That piece was from the underneath that fell off, it did have a tail, first look it reminded me of a stingray shape, I need to start taking photos before I remove !
