Greetings @liam-wallce ! I concur with @daniel-park that is probably a concretion.

@daniel-park hey, you’re right! l see that now! post more images with different angles to confirm for sure what it is, @anthony-c

@daniel-park l’m thinking wood is more likely

@daniel-park I heard that in the 80’s all the dimetrodons were getting perm-ians

Thanks @daniel-park! These are relatively old museum dioramas that were made into 3D so we didn’t have much say on the animals! Cenozoic dioramas coming eventually!

@daniel-park mozzies are truly annoying. but they don’t necessarily have to be of use to humans. no animal has to. animals evolve to do something that keeps them alive. mozzies saw these walking blood tanks and thought “hey, there’s a food source nobody else is using. let’s take advantage of it.” if there were no mozzies, humans and flowers would…[Read more]

@daniel-park rudimentary knives or cleavers. they are rather irregular you can see, instead of perfectly triangular like many indian spearheads. the south American natives remained quite primitive for a while, and had reached an Egyptian level of civilization as late as the 1000s and beyond, with the aztecs and incas

@daniel-park truly fascinating. happy to see some answers. l was thinking, the shells of tube worms who grow on rocks and intertwined with coral, resemble those of some heteromorphs like Nipponites. maybe they also lived sedentary lifestyles with shells adhered or tied around coral branches, sticking out their rim of tentacles to filter feed?

Well guys, remember that ammonites are just orthacones that curled up their shells. That transformation took place from the devonian to the Triassic. In between straight and tightly coiled shells you find in between ones such as this. Triassic was a guess because it’s so high quality I wouldn’t think it would be as old, also the shell is ridged…[Read more]

@daniel-park l did some research on Maclurites and it’s a gastropod. this fossil is of an ammonite. so the conclusion is that this can’t be a Maclurites specimen, and must be some ammonite

Partial bone? I found something else similar to this a while ago, except it was grey and the bump was much less prominent. I’m curious to see what this is, so I’m going to call on @daniel-park

Thanks @daniel-park !

Greetings @bo-nichol ! I believe this is just a rock, but it’s somewhat difficult to tell. And thank you @daniel-park !

Yeah cheers @daniel-park

Thanks @daniel-park !!! It’s a possibility, but it still looks like a pseudo-fossil to me. It’s frankly hard to tell from this photo. I really don’t see anything distinctive like porous cellular structure that would indicate it’s bone. Also, here is a myfossil tutorial for improving photo quality and digitizing your collection:…[Read more]

Thank you for including me @daniel-park !Greetings @jack-parker-tyreman ! If you could load up a few more photos it would help to clarify whether it’s bone or not. If it is, there is not much in diagnostic features to provide a precise ID I’m afraid.

still… It can’t be a limpet. some is still imbeded in rock so @daniel-park could be right

@a-trilobite it doesn’t look like a limpet…. I’m going with @daniel-park

@daniel-park it could be worn, whatever this is it doesn’t have detail, it has shape. And the shape tells me that it’s a horn coral.

@daniel-park It’s not that, I was thinking maybe a limpet?
