I haven't shown you my latest additions to my rocks, fossils & other nature stuff collection yet. So, brace yourself here it comes:
First, from sunny Croatia (Drage, near Biograd); Common Sea-urchin tests


And this little one, which still has some spikes attached

Also a large Sea heart (compared with one from Holland)

And from Kampen, Holland:
One of the lower cheekbones from a horse. Fossilised of course.

with the teeth still attached

My youngest sister and her friends dug it up from our street while the drainage was renovated. Pretty cool, huh? Proves that there used to be farms where we live now.
