Partial foot/limb - frog?

Recommended Posts

Hello, any thoughts on this?

 

It is a slab measuring 12 cm x 9 cm with three partial limbs/foot fossils on. The largest foot measures 4 cm, then the longer limb bone heading right 5 cm.

 

At first I thought it could be a frog--but the circled, possible partial dew claw throws me. I am not aware of frogs having a dew claw. Which makes me think it's a type of bird. Hope the pics are ok--seller (doesnt have the fossil on hand) is gonna try and get more, but the collector is away.

 

It is from China --Jehol Biota, JianChang,

Looks very much like a partial leg from a theropod/bird with a tibia or fib, 3 metatarsals and its foot that is all jumbled up.   I don't think its a dew claw you are seeing but a part of metatarsal III broken to the side.  Do the foot bones have any relief?    I think I see a claw in the center of the foot but the images are not the sharpest and will need better ones.  Interesting all I can say.

What is the meaning of relief?

three-dimensionalness, if that helps.

I've bought the fossil as price wasn't too high and was in my budget. I'll take some close photos when it arrives--and other angles, see if there's any signs of the bones been hollow etc. See how 3 dimensional it was

@Troodon

The fossil arrived. Unfortunately, a bit more battered than it seemed on the original pictures--and, very, very fragile. There are three fossils--found on same slab.

 

Pics 1- 6

 

This is limb one--given the fact the longer leg bone is split and looks hollow, that means it is likely a bird? The digit bones are veyr, very tiny.

 

7,8 and 9 - limb 2

 

 

9 and 10 - "limb 3 -- is this a hand, rather than foot? 

 

 

I'd love to hear your thoughts.

 

Thanks

Can you provide better focused images?  These have very little detail.

Can you also number the photos so it's easier to refer to them

I will get better photos soon. Sorry for late reply--I have been in hospital the past couple of days, so hadn't had time to check. 
 

Cheers
