A digital repository of bones and fossils available from the University of Michigan lets you look at fossils in 3D. The free online tool lets you rotate and zoom hundreds of specimans and get a better representation of archeological finds.
Initially it was intended for palaeontologists to examine and identify fossils, but it became a free resource for students and the general public. The collection of three dimensional bone models is expected to increase into the thousands as more items are entered into the data base, giving you an even more comprehensive view of these prehistoric creatures.
The University of Michigan Online Repository of Fossils not only lets you look at fossils, it also includes a 'BonePicker' feature that lets you pull from a skeleton and look at photorealistic images up close.
