Teachers are raving about this amazing kit! Students will identify and classify microfossils that are over 375 million years old! Microfossils are small fossilized remains of organisms that, when viewed under a stereoscope, open your student's minds to the past. Students will obtain first-hand knowledge about the types of fossils found in Devonian period limestone. Kit includes thousands of microfossils, an informative microfossil CD-ROM, and enough microfossil manipulation tools for 30 students working in pairs. A stereoscope is required and is sold separately.
