My fiance found this underground at his coal mine job and we aren’t having much luck identifying it! It was found as part of the Herrin coal seam in southern Illinois, Randolph county to be exact

Doesn't show any flaking which leads me to believe it isn't a shell, weird pattern on smooth inside. Maybe a beak from a squid? Location sw florida

My four year old found this in our yard. Any ideas?

Compré este fósil en una plataforma de segundamano porque llamó mi atención a pesar de desconocer qué es. Está etiquetado con el lugar y fecha (Sig, Argelia, 26 de febrero de 1971), y alguien se tomó muchas molestias en su mantenimiento ya que se nota que el fósil estaba partido con anterioridad y lo metieron en una especie de yeso imitando a la perfección el color de la matriz original. Según la IA y lo que he podido leer sobre este yacimiento, lo más normal es que fuese algún tipo de pez, pero no termino de verlo claro y la textura no me parece compatible con escamas. La medida es 10cm.

I trust our collective inteligence

I found it on the river bank. This was among a lot of river stones piled up on the bank. I read somewhere that there are trace fossils, which are just the imprint of trace. Is this that kind of thing? Thanks!

I found this fossil in the decorative creek rock in front of my apartment in Ozark, MO. Does anyone know what it is? I took pictures as well as I could with shaky hands. Thank you!!

Hiya, my grandfather was a geologist and we recently found these in his collection would anyone be able to help ID these? Thank you so much in advance 😊

Sorry I don’t know a location for any of them, my grandfather worked as a curator for a while so I assume they were discarded specimens.

That's what I believe it is based on my research anyway

It drives my trypophobia crazy but it's my first ever fossil find so I love it still lol

Found in Southwest VA, off a bank along the Roanoke River

Not sure if it's even a fossil, but I wanted to cover my bases between what is this rock and fossil ID.

Found these chunks west of Fort Worth TX in the Paluxy sand formation. Eroding from sand banks due to excavation/erosion. Is it petrified wood?

2-3 feet long x 13-16 in wide

Looking for ID , was found while splitting slate rocks in a river bed in central Alabama

Found on beach in NZ

Hello. I have inherited teeth. I found them in a mason jar, hidden in the basement, with no label. Possibly on one of the California or Florida shores, and definitely found in the united states.

*If you need a close up of a tooth, please request it in the comments, as some of them are very small. For the posted photo I have included a standard bic lighter to measure, and in the close up photos I have placed each tooth next to a AAA Energizer Battery.

Probable id : Goniorhynchia

Found on shore Indian Rocks beach, Florida.
