We found this bone on the shores of the Thames at Chiswick today 8-8-2013
It's 180 mm long
It weighs 279 grams
The circumference around the top is 18 cm
The circumference around the mid point is 12.9 cm
The circumference around the lower end is 10 cm
It feels like stone and looks like a human tibia bone with ta hollow centre but it is definitely fossilzed.
My grandson Sam and I would be very grateful for any help in identification. We wondered how long it takes for a bone to fossilize?
Many thanks for any help you can give us.
It isn't a human bone. It's from a quadrupedal (four legged animal) but difficult to tell which as it is broken. Not really fossilised either I'm afraid (although I understand why you say that as animal bones can be very dense and heavy). It has clearly been in the water a very long time though as it has worn some of the features away.
Thanks so much for your helpful reply. I will break the news gently to my grandson! Best wishes, Eucalyptus
not good at this .. bone but i found a hunk of bone nr richmond bridge thinking it was mammoth but was told by museum i was cow ... althoug hit as heavy and felt nealtly like stone .. So similar dark brown colour too
Thanks for that. Somehow a cow seems rather boring. I was hoping it might be Cro-magnon man or somesuch! Best wishes.
