Excellent point. The vascular bundles in Palmoxylon have a nonlinear look to them, while the overall shape is nearly straight. Disregarding the end grain, this piece does look more like another type of wood. Edit: Maybe I am taking it a step further. Just noticed that.

There was likely fluid in a void that the concretion formed around. That allowed space for the crystals to form. The process is known as geodization.

Yeah, they're often misidentified as elasmosaurid. But elasmosaur teeth would be both labiolingually compressed and have much finer striations. Here are a couple of Russian examples for comparison: -
Last time I went there, it was so mobbed with kids, I left after 15 mins. And it wasn't school holidays

I bought this Croc jibbitz recently My teenage son & daughter have remarked this this is more for little kids

Cheers for the replies, its hard to show in the photos but the inside is all crystallised with a sort of webbing going from the centre to the outer edges

I agree w/ concretion; a nice septarian nodule, I'd say.

Spinosaurus Tooth, is it real?
Samhain replied to Samhain's topic in Is It Real? How to Recognize Fossil Fabrications
Yes it is from the Kem Kem, what genuses of Spinosaurid are usually found there? Is it the Sigilmassaurus, Spinosaurus Aegyptiacus and any other genuses? From what I’ve read, there isn’t any way to tell the genus by the teeth, is that true? -

Is polycotylid tooth? Great! I love this clade. I bought the tooth as elasmosaurid, but i prefer polycotylid. @pachy-pleuro-whatnot-odon -
It looks like a concretion to me. Which are found in Pilbara,e.g. in Banded Iron formations

Hi there, I have no experience with fossils or Geology but found this which to my untrained eye looks like some sort of egg. It was found in the Pilbara region of Western Australia. I was hoping someone here could help me identify it please

Given what looks like a bit of reasonably preserved vascular anatomy ,there is the distinct probability that is (fossil)palm wood edit one:spelling,punctuation edit two: I get what JohnJ is saying I am a proponent of detailed anatomical investigations of fossils.. the actions of wood decaying fungi can lead to delignification of cell walls,but how that would show up macroscopically i am not sure

Ok, thanks. I will delve into those a bit more. Is that based on the shape of the root? Is there something in particular I can read? I’m happy to do that if I have access to it? Thanks

@johnnyvaldez7.jv You say this piece is only two inches long...so that makes these end grain 'dots' pretty small. Can you get well lit, sharper images of the ends and sides? I'm leaning toward palm, but "pocket rot" in the vascular parts of some wood types can mimic palm or snakewood.

Here’s a pretty incredible trilobite I collected that was prepped earlier this month! • Date of Discovery - Found:February 20 2023, and prepped March 19 2023. • Scientific and/or Common name: Isotelus gigas • Geologic Age or Geologic Formation - Upper Ordovician 455 mya • State, Province, or Region Found: Lafamilia quarry, New York.

Presence of the nutrient groove rules out Cretalamna, these are all goblin sand/tiger, I may return to the topic this weekend to see if I can better determine between the two. These do look like a mix of "symphyseal" positions, and perhaps intermediate? Technically speaking, rostral teeth are just giant (modified) dermal denticles. This is a denticle, the question of whether this is from the rostrum or not would require some reading on my part.

Ha, so alllll the way back to the beginning, where the small size is confusing! I’ll read up on the species of peccaries tomorrow. My guess is that it will be the smallest species. Challenging identifications are so much more fun than easy, normal ones thanks for all of your help I appreciate you!

Spinosaurus Tooth, is it real?
Troodon replied to Samhain's topic in Is It Real? How to Recognize Fossil Fabrications
Yes its a Spinosaurid cannot say which genus it is from the Kem Kem -
Perhaps @Carl could run the photos past Dr Maisey for an opinion. Don

Spinosaurus Tooth, is it real?
Samhain replied to Samhain's topic in Is It Real? How to Recognize Fossil Fabrications
I have some more photos from other angles, in these photos I’m able to make out two carinae on both edges of the tooth. -
Really nice piece of pet. Palm wood.

Honeycomb points to theropod and its size suggests that it could be tyrnno.
-
So, here is where we started , we did not know very much and your find looked very hard to identify. We have learned a lot, made some progress, but it is still hard to identify.... I think it is Peccary, not Platygonus, but possibly one of the 6 species of Mylohyus that were present in Florida's fossil record. For reasons specified above, I think it is lower jaw... and I think it is a premolar.... Even as Peccary goes, it is a very small tooth... This one is Mylohyus elmorei upper jaw p2-m3 just in case I am wrong
-
I seen you mention the honeycomb structure before and that made me even more curious. & yeah if it is theropod it’s gotta be tyrannosaur right? Way too large to be anything else in this formation.
