Napoleon North Posted February 20, 2018 Author Share Posted February 20, 2018 My answer. I found the bone in a deeper chamber of the cave. Link to comment Share on other sites More sharing options...
LordTrilobite Posted February 20, 2018 Share Posted February 20, 2018 Well it's definitely a left femur. Though from what animal I don't know. And it looks like it could potentially be recent. So as Kane said, using the burn test might help. 2 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

Kane Posted February 20, 2018 Share Posted February 20, 2018 The burn test would help determine if it was older than a subfossil (~50,000 years old). Also, a number of your finds from this cave have been from recent bones, so it is not an unreasonable request to make to narrow down the possibilities. Perhaps appealing to the academic literature as opposed to commercial sites would be a much more authoritative source, in this instance. We are sorry that you are experiencing a loss of trust with the forum. We can only do so much with images. Members are always free to disagree with the identification, and are encouraged to take the specimen in hand to a paleontologist to confirm the identity of the specimen. 8 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

You have posted several pieces of fox bone and teeth which have been identified by others and me as being fox. How are we supposed to tell the age? It could be a fox that wandered in and died a few years ago or be much older. A burn test helps narrow down the possibilities but we cannot tell the age for sure just by looking at the bones. It looks recent to me, but may possibly be older, a burn test would exclude the 'petrified' option of one of your links. 5 Life's Good! Tortoise Friend.

I told you what type of bone it is. And I don't know how old it is. And as Tidgy's Dad points out the burn test can help finding out how old the bone could be.

DatFossilBoy Posted February 20, 2018 Share Posted February 20, 2018 Napoleon North, Does not look fossilized to me... the bone ressembles more the bone of an animal living in our period. Sorry you are losing trust in the fossil forums even if I don't know why,after all the fossil forums is created for us to give advice and clues to the person who posted the picture wanted to be identified.The messages being send are full of information to help you.

indominus rex Posted February 20, 2018 Share Posted February 20, 2018 Am I the only one who is confused? Why suddenly delete this account? Also it's kind of hard to tell the age of a mammal bone just from a few images, but why does this mean you trust the forum less. All we have presented to you are what we can tell from the image. But sorry that you trust the forums less. 1 Life started in the ocean. And so did my interest in fossils. Link to comment Share on other sites More sharing options...
abyssunder Posted February 21, 2018 Share Posted February 21, 2018 I know you're trying to give your best, but understand that's not easy to determine bone's age in cave formation due to the specific weathering and depositional conditions, especially if the bone is an isolated one. An advice, which might help us and you, is to take photos of the specimens - 'in situ'. Also, archaeologists might help you.

It is at least the second time for which you ask us to delete your account ! Members do their utmost to help you, but they can't make of miracles !
