mollusc doesn’t look fossil but looks like some of my shells which are 40mya so I class them as fossils🤔
was it found inland?
@leonardo-miranda yes, never found it on surface
probably fossil then
since it isn’t near a water source
that snail is evidently aquatic, so if it’s found inland then it must be ancient
@leonardo-miranda closest river is about 7 km. But there is salt water lake 200m from my house
@leonardo-miranda in that lake there is no living creatures
interesting
if not fossil, the shell should have at least some centuries/millennia of age, from a time when that river was flowing through that area
@leonardo-miranda the more deep I dig the more stuff I find
Okay so a couple things. The first one is a snail can live on land. Gastropoda are the only mollusk to develop lungs which are snails who some evolved to loose their shell giving us slugs. We have a very similar modern day snail that lives in our mountains here in Logan. It’s pretty funny because it bleaches when they die so people bring them into my department all the time! Anyways, while that is true yours is definitely a fossil. I know this because it is filled with lithified (glued together) sediment that is at least strong enough to hold the shell together minus the offset fracture. It may not be very old and that is most likely the original shell but it has been buried, lithified, and then brought back to the surface making it technically a fossil.
@neven-popov-2 Hi there! You can go ahead and fill in the taxonomic information as Kingdom: Animalia Phylum: Mollusca and Class: Gastropoda!
gastropod
@chloe-geddes l was thinking that gastropod was an aquatic species because that shell shape seems to be more common in aquatic snails than in land snails. for example, the freshwater rams-horn snail. but l guess there are a few landliving species that have the same flat spiral shape too.
@leonardo-miranda, you’re a very smart kid and I’m always very impressed with your comments ☺️Shell morphology is super complex, it can evolve the same style of shell at different times and this happens much more frequently than you’d think so while rams horn snails have similar shells so do some land living snails. Now this could be a fossil rams horn, I don’t know how long they’ve been around…
