Many people who collect minerals think limestone areas are kind of boring because it does not have the great variations of different minerals as we find in volcanic stones.
But i think they are amazing because of many other possibilities they give, like all the caves that usually is in them, and the possibility to find fossils and petrified plants and animals.
Close to where we found this "claw"(i am not 100% sure it is that) there is also a area of marble.
The limestone there was turned in to marble because of volcanic activity close to it, but that limestone had a lot of fossils in it, so it is a amazing marble full of fossils/petrified plants. (i shall try to remember to take a picture of it one day and post in another post)
Anyway, here is a couple of photos of the "claw"(bad photos from a mobile phone that might also be from the same period as this fossil / petrified claw..) ;)
(To me it look like a part of the front leg)
Its almost the same photo, but since it is so bad quality, i can post both..
Its about the same size as a very big foot.
It is not for sale, if it turns out to be a real claw, it will be given to the geological museum in Oslo. :)
