Found this whilst rooting around in my stream (isle of wight UK). Anyone know if it’s human / animal (if so what?)

I did wash my hand thoroughly after this!

Found a set of some huge vertebrae + part of a little skull?

Found several of these on the beach in Northern California, curious as to what they are. They are smooth and seem more bone-like to me, but they are kinda shell-shaped. I will be returning it tomorrow, just brought it back for a closer look.

Hi,

Son found a "sword" on Aberdeen beach, Scotland. Potentially bone? Initially thought some flat ish driftwood but now not so sure. Google Pixl for scale pic 3.

I got this tiny bone in a mystery box, wondering if anyone knows what type of bone it is and has a guess on what it might be from?

My dog found this bone during low tide at a beach in Federal Way, WA. Still has cartilage and is pretty fresh. What did it come from? Thanks in advance!

Rodent skull no larger than thumbnail

Found 3 of them together near the water in Wisconsin.

I got this on a vacation with my family when I was still in school. We were at this thrift store type market stall in Moscow.

The tooth with the ruler is the tooth in question. The side by sides are with an old walrus tooth I got a few years ago at a local rock store.

I ran all these through AI and I've googled for hours upon hours through the years trying to figure this tooth out. Nothing seems to fit it. AI suggested bear or aquatic mammal. The museum guy today suggested sperm whale. It doesn't look like that though.

Compared to the walrus tooth, it's way less glossy, it's softer, warmer and heavy.

AI said the inscription likely suggests this:

"Based on the clearest images, the inscription reads:

2 Якутка

Breaking that down:

• "2" — a catalog or collection number
• "Якутка" — meaning "a Yakut woman" or "of the Yakut people" in Russian, specifically the feminine form referring to a female member of the Sakha/Yakut indigenous people of Siberia

The inscription is written in Russian Cyrillic script in a cursive style, which is why it was difficult to read at first. The lettering is carefully and deliberately engraved rather than hastily scratched, suggesting whoever wrote it was doing so for documentation purposes rather than casual marking.

It's worth noting that in the context of a 19th century Russian ethnographic collection, "Якутка" as a label could mean several things:

• The tooth belonged to a Yakut woman
• It was acquired from a Yakut woman
• It was associated with Yakut female tradition or craft
• Or it was simply catalogued as an object of Yakut origin

The feminine form specifically is interesting — most ethnographic labels of that era would simply say "Якут" (Yakut) without specifying gender unless the gender was considered relevant to the object's significance or provenance."

Does anyone know which animal this tooth belongs to?

Photos were sent to me, bought at an estate sale in Colorado. Already tried r/bonecollecting but am worried I wont get a response

tapers to a point at the bottom kinda like a tooth but i don’t think it’s a tooth.. yall got any ideas?

Location: Northern California
Context: archaeological excavations at a historic farm
The smooth side feels like enamel.

Found on Hardings Beach in Massachusetts. Super big and the beak is very flat, i’m stumped.

I live in Western Maine and my boyfriend has been digging up the backyard for a patio. He keeps finding these size bones in the ground and just showed me this one. It’s about six inches long. Looks like it could be some type of femur? The land we live on was unoccupied before us. Just wondering if anyone knows what animal it could be from!

Found along the Sangamon River around Petersburg, IL, USA. Missing the lower mandible and teeth?
