Jurassic Ichthyosaur From The Uk

Recommended Posts

Hi

This is my first proper post, so here goes.

Me and my brother found an ichthyosaur over the Christmas holidays. We picked up pieces over a number of separate days. The ichthyosaur is from the Lower Lias, Hettangian, and I thought I'd upload some pictures to share. Here are a few of the pieces as found:

And here are these pieces glued back together and ready for prepping:

The glued piece is approximately 18 inches long and the bone has been covered in paraloid to protect. You are looking at a set of ribs, a disarticulated front paddle and some bones from around the eye, plus a couple of the sclerotic plates.

Assuming this has worked, I'll post some other pieces soon.

Hi Nick,

That is an excellent find, was this one found at Lavernock? I have a few pieces from that area but nothing as grand as this, very well done! Welcome to the forum by the way.

Regards,

Quite a transformation: good eye to spot them!

Icthyosaurs are such iconic fossil beasts; as a child I regarded them with the same reverent awe as T-Rex...and still do, in truth. :)

That looks like a mosasaur vertebra right in the middle. Is it a paddle bone?

Hi

Thomas. Thanks for the comments. Yes it's part of the same one. The other bits I have are still in a box drying.

Boneman. The bone in the centre is the humerus from the front paddle. The radius, ulna and other paddle digits are scattered to the right and bottom of the piece.

Auspex. It is an iconic fossil. I'm not sure what species this is, but it may become clearer on prepping.

regards

Hello Hick,

That’s a great find well done to the both of you. Was it like all Christmases rolled into one? Have you considered an Ichthyosaurus brevicepsas a possibility they are off the same geological age.

Hi

Steve, I have part of the skull and the disarticulated rostrum, in another block about 18 inches long. I'll post soon.

Darren, thanks for the suggestion. When I post further photos, you'll see that the rostrums quite long so its probably good old ichthyosaurus communis.

Regards

Nick

Great find!

I have an ichthyosaurus communis in my collection and it is still my best fossil to date I love them!

Hi again

some picture of the skull and rostrum bits:

The first picture is of half of the skull. It's upside down, so you're looking at the inside of the skull. The bones pretty rotten:

Picture 2 is of skull reverse prepped. The opening on the top of the skull cane be seen and the eye socket with some sclerotic plates is showing:

Picture 3 shows the rostrum bits as found:

Picture 4 is the splayed bones of the rostrum bits after a light clean. The end of the jaw is broken off and some teeth can be seen spread around. The teeth are about an inch long:

I'll post some more as things progress

Thanks for the comments

JWCounts - It was found in Late Dec 2012/Early Jan 2013 and I've only just joined the forum so I'm not sure if I'm allowed to enter as fossil of the month? Any help appreciated.

Evgeny - It probably won't be prepped out of the matrix but I'm just pondering what to do. The paddle/ribs will probably prep OK but the skull bones may have to be backed and reverse prepped. In April, I'm going to take it to someone who knows how to do this sort of thing and they'll have a look at it.

regards

That looks like a lot of fun, I'd love to get my hands on that. The skull might be touchy, but the other pieces would be great to prep. Good luck!

I went back to the see if I could find any more of the ichthyosaur today.

Unfortunately, after searching the rockfall for hours I was unable to locate any more bones. They are either still in cliff, lost to sea or drifted away prior to fossilization.

Good news is that i did manage to pick up a few pieces of mudstone that contained the ammonite psiloceras planorbis, which confirms that the ichthyosaur is from the earliest part of the Hettangian.
