I we went to the south of Sweden where we found all sorts of fossils ranging from amber to belemnites.
The Baltic amber was found in the seaweed, the coral is found in the shingle and the other fossils are found among the larger stones along the foreshore.
Hope you enjoy them!

Hello Thomas,

Nice fossils, especially the echinoids. However, the spine on the picture with echinoids looks a lot like a spine from a recent Heterocentrotus mammillatus, http://echinoids.nl/Echinoids/Heterocen ... latus2.htm, but I've no idea how it got to Sweden, since that's not really within it's distribution area, http://www.nhm.ac.uk/research-curation/ ... jsp?id=967.

Hi Bram,
I agree with you, but I have got some other specimens of un-fossilised sea urchin spines, and when you tap it against a tooth it doesn’t sound the same. Do you know why?

That could be caused by different internal structures of the spines. There are several different kinds of spines, based on their internal structure and some are hollower then others, which may cause differences in sound when tapping it to your teeth.

Greetings,
Bram

Thanks for the help!
