Lobster from Lyme Regis?

[Max-fossils]

Hello everyone!

 

First of all, I would like to say that I am new to the website, so if I am doing something wrong, please notify me!

 

Second, I would like your help identifying this fossil lobster I found at Lyme Regis (Dorset Coast, England) 4 years ago.

I am pretty sure it's a lobster, as a local paleontologist (Paddy Howe) said it definitely that; but he said he had no clue to what species it was.

Here is some basic info about the fossil:

Age: 200 myo, Sinemurian stage of the early Jurassic

Size: from left to right, around 4cm

Important: the head and the tail are missing!

As there is no head nor tail, I would understand it is difficult to determine which species it is, but I would still be happy if you give me an opinion.

 

Warm regards,

 

Max

It is a lobster for sure, but nothing more from my knowledge to complete the request.

It seems to be several leg segments, without any of the body.  It's definitely a crustacean ("lobster") but I don't think there is enough there to go beyond that.

Thanks a lot for your replies and help!

It doesn't surprise me you can't ID it, I know it's hard.

 

Warm regards,

Don is right ...

Try to search in the context of Hoploparia, eventually try to prep carefully the fossil, or, if you think is necessary someone specialized in this, please do not hesitate to appeal  to that .

I looked at Hoploparia, but I don't think it is that, because it seems a lot larger than my fossil. Perhaps mine is a juvenile?

As to for the prep, I don't have the tools for it, and I've never done it before... Do you eventually know someone who can do that living in the Netherlands?

 

Thank you so much for your help!

 

Warmest regards,

It won't be Hoploparia as the ones from there are all Cretaceous, Upper Greensand. 

The most likely Sinemurian ones are Pseudoglyphea or Coleia but I don't know if it's possible to tell with that one.

Hi,

 

Thank you for the clarification, but I think you're wrong

I looked up when and where Hoploparia lived, and saw it did live in the Jurassic and has been found in Europe.

On one website I even saw a specimen found in Lyme Regis.

But I still thank you for your help, because I saw Pseudoglyphea and Coleia are also possible, even though I do kind of doubt Coleia a little bit.

So you basically made it all more complicated and confusing for me, but at least I don't have wrong information!

 

Thank you a lot for your help!

You're welcome! As far as I know, the only Hoploparia found around Lyme Regis is H. longimana from the Cretaceous Upper Greensand where it's something of a classic (I have several). I don't believe there are any from the Lower Jurassic there.

I'm quite confident that Hoploparia is a Cretaceous genus and does not occur in the Jurassic.

Ok, well thank you for all the info!
