Please help to identify this heart shaped bone found on my local beach today

[Dorset_Belle]

I found this bone? on a beach walk this afternoon after a stormy couple of days weather.

 

I'm not sure if it's a fossil but was wondered whether it could be a rostral node?

 

Found on Branksome Chine Beach, Poole UK.

 

Thanks in advance.

Hello Dorset Belle and welcome to the forum.

I think what you found is the distal end of a femur, what is called an epiphysis, that is the part of the bone that is separated from the shaft by the growth line. Especially in young animals it separates easily from the long bone.

Best Regards,
