Whilst on holiday in Cefalonia 10 years ago I found this fantastic fossl of a complete lizard like creature.
I would really like to know how old this is & if possible what is this animal.
There is also a chunk of fossilised tree going through the whole piece & various other debris & indentations.
I could bring it to you when next in London if you are interested.
I live in Norfolk.
I, er, don't see the lizard...
But I'll give the NHM staff a nudge to make sure they take a look soonish, and so they can comment on your bringing it the the NHM (I'm sure it would not be a problem).
Sorry Sheila, that's not a valid interpretation.
The 'curled' structure is a fossil, certainly, but it is not a lizard. You can see enough of it to imagine it in 3D - and it is more cylindroidal in shape, or perhaps ovoid. The bit you see as a tail: that tapers off just because of how the rock has broken. The bit you see as an eye: that's just an accident of erosion (and if it was an eye, it would be in a distinct head - not the rounded end of the curled structure). The bit you see as a leg: that is significant, but it is not a leg (it is not jointed).
To some extent this looks like a cross-section of an echinoid, just off-centre. But the thickness of the shell is too great (there's a cross section at the top of this page, which includes bits corresponding to your 'leg' - http://www.bgs.ac.uk/discoveringGeology/time/Fossilfocus/echinoid.html). There is also no sign of the plates that make up an echinoid's shell.
Oystes can have shells thick enough to match your specimen, but I don't quite see that as the ID.
Awaiting comment by NHM staff in due course...
