Like fossils? Here's a great site for looking and learning...and maybe purchasing them.

There are paleo tools, fossils of every kind (I love those crinoids), like perfect dragonflies...be still my heart.

It's not just for the grown ups, it's like a museum tour. Nice little enewsletter, too of new finds and old things (pun not intended).
