In paleontology, sometimes a find that is not much larger than the head of a pin can yield surprising insights into our planet’s past. One example is a partial tooth discovered by Ohio University researchers in 2003 in southwestern Tanzania. Although this discovery was not a complete skeleton or even a complete tooth, it preserved just enough information to lead to a discovery about how the earth’s plates are moving in the East African Rift.
Other discoveries uncovered by Professor Stevens include evidence of one of the largest meat-eating mammals ever to walk the Earth, as well as six new species of invertebrates.
