Cretaceous Fossil ID from Saudi Arabia


JemB

Recommended Posts

Please could anyone help me with the identification of these fossils. I have very limited knowledge so appreciate any comments. All fossils were found in Thumamah Park near Riyadh in central Saudi Arabia and all were collected loose from the ground. The age of the formation here is Cretaceous according to the geological data I can find. The bottom two photos are two sides of the same fossil which looks to me like an oyster of some sort (but could be totally wrong).

 

Thanks in advance for your suggestions.

Hello JemB and welcome to the forum!

The last one does look like an oyster to me too, there will be someone around who can tell you more.

The elongated form on the one before that could be someting like a Turitella gastropod that has been opened by erosion.

The first one looks really interesting, but I have no idea what it is.

Just wait a bit, more often than not someone on this forum will know more.

Best Regards,

J

The first one still intrigues me though.

Best regards,

The first two pictures remind me of rudists.

Thanks for the help. I found the two fossils abyssunder mentioned as possible rudists next to some much larger examples of rudists which I attach photos. I identified these from the below paper found on the internet. The location I found my examples were about five kilometres away from one example they quoted and some look very similar to plate in paper (e, f).

This would help confirm them as suggested as rudists I think.

Your last photos show clearly the commissure separation between the lower and upper valve of rudists.

Sorry for my late reply, I missed your response. :)
