Very interesting looking specimen! Love it @nathan-newell!

Same story with this one as my previous comment @rob-peart!

@rob-peart, as @patrick-hsieh said this looks like a Trilobite, making this Animalia, Arthropoda, Trilobita–without the head it’s difficult to classify past that! Very cool! If you know the location of the riverbank you got this from we can fill out the geochronology and lithostratigraphy of this specimen as well!

Hi there @liz-allan do you have any more specific location information and a photo that more clearly depicts the specimen? That might help with IDing it!

Very cool specimen! Perhaps @mackenzie-smith can help with ID!

Wonderful specimen!

Wonderful!

@mackenzie-smith same with this one!

Very cool! @mackenzie-smith might be able to help with the ID here!

Hi @sarah-mosteller@smoran might be able to help with this ID! Very cool find!

Very cool find! Do you have a picture with some type of scale next to the specimen?

@aiden-rouse Do you know the Lithostratigraphy of the site where this was found? Sites like macrostrat.org can help you narrow it down!

Two lovely ammonite specimen @sara-andrade do you have any location info for these?

Hi there @adomas-rutkauskas do you have any location information for this specimen?

Hi @sam-e This is just a very interesting pattern in a rock!

Hi @greta-stroebel I’m afraid it’s going to be hard to ID without a better picture! Perhaps try setting up a flashlight closer in to light the specimen?

Hi there @james-brooks this does look like a worn piece of horn coral!

Hi @dale-simpson if you could fill out the location information that helps greatly with ID! Sites like macrostrat.org provide info like lithrostrat and geochron based on the location. This helps with ID of the specimen! @jack-parker-tyreman while I can see the similarity to an ichthyosaur eye socket, the shape and the fact that the material does…[Read more]
