I like fossils. We once found a rock made of fossilised marine creatures. Must've been on its way to becoming limestone or whatever that rock is before it fell off the cliff.
Good for you!!! I fossil hunt in a river and have found several. I get sooooo excited when I find 'good stuff'! The most common thing we find is small sharks teeth. We have also found lots of other bone pieces, horse teeth, stingray mouth plate pieces, agatized urchin spines, horse teeth, alligator scutes, fragments of mammoth teeth and more. I will have to dig some out one day and take pics to post.
