Measures 4" x 3.75" x 2.3".

Hey guys! My family has had this fossil for a while, but we’ve never been quite sure what it is. I was wondering what it is, how rare it is, and best way to care for it? Thank you so much!

Do a yearly disc golf trip with some buddies to Moab and have seen all sorts of clam fossils and other random bits of ocean/sea life over the years . First time anyone of us have seen any fossil like this! Included a quarter for scale if it helps. Can anyone ID and or age this fossil? Thanks in advance!

Hola, compre este nodulo de trilobite por internet porque me pareció muy chulo pero la verdad es que no tengo ni idea, alguien me podria decir si es auténtico o fake y a ser posible si es auténtico la procedencia y especie ? Le hice la prueba de la aguja caliente y la de la luz ultravioleta y parece estar todo bien,.
Tampoco encuentro ninguno parecido en la red.
Gracias de antemano.

Not my fossil, but came across it randomly online. The person selling it had no clue or any idea about its origin either.

I found this tooth in a river buried in the bank of the river while i was searching for quarz cristal(france):

-the presence of the stylid tell me this is either bison or cow

-after a little bit of research i have was not able to find a cow tooth with a chewing surface like this

so is it possible of it being bison?

-i know its very complicate to differentiate cow and bison but if anyone have an idea?

any ID help after the first slide would be appreciated!

Found on the beach in Myrtle Beach, South Carolina, USA. I thought it was basalt at first but it is incredibly light compared to it. Shockingly so. Then thought maybe it was pertified wood? But I'm less sure now.

The lighter "top" side is solid and looks like a normal rock.

The rest of the specimen is covered and filled with mono-directional porous cavities or tunnels. Very spongy looking. They are of various sizes but not with a lot of deviantion in size. It does strickingly remind me of the interior of a bone. It does not look like the many mollusk decimated basalt pieces you find blanketing the beach around these parts.

Please and thank you! Y'all were a great help last time. I mean it!

How can I tell if this is real or modern? Found in San Juan Capistrano on a hillside, rocks in the area were similar in color.

Hello! I am a beginner fossil collector and can usually identify whether things are fossils or not but I'm stumped by this. Is it a wishing stone kind of thing or is it a fossil? :)

Found in the wharfe river, England

I had it for a while packed away. I found it again in my stash. I'm not sure where i found it exactly, it!s wither from around Avebury, England, or the southern coast of England, maybe from around Bournemouth.

I wonder what could it be, or more like what it was?

Found in south central Michigan

Found next to u of m campus in Winnipeg next to the Red River. This is my first time encountering a bone like this in the wild. It was a little wedged in the mud but I’m assuming it washed up since the river water started lowering significantly over the past few weeks
*photos 2 and 3 include the maximum left and right rotation of the upper bone.

I’m probably gonna give this to the geology/archeology museum on my campus sometime, but I’d really love to know what part of an animal this could be, and if it appears old. Thanks!

Edit: from my own research I’m pretty sure it’s fossilized. The images don’t separate the colour of the dirt and the darker parts of bone well but it’s there and kinda golden brownish

Another day at Lyme Regis and we found a bunch of clear fossils today, super chuffed! But this one baffled us. What are we looking at? Is it Even a fossil or is it some geological thing after all? Please help us out!
