Fossils 101 - And How Scientists Know What Color Dinosaurs Were

National Geographic's YouTube channel has a great series called 101 Videos. The series contains 115 videos that provide five minute introductions to a wide variety of science topics. Fossils 101 is one of the recent additions to the series.

Fossils 101 explains to viewers what fossils are, fossil types, how fossils are formed, and what fossils can reveal to scientists about the past.


On a related note, a few years ago TED-Ed published a lesson titled How Do We Know What Color Dinosaurs Were? The video explains how scientists examine the melanosomes of fossilized feathers to determine the colors of some dinosaurs. The video then goes on to explain how the physics of light and color eventually lead scientists to their conclusions.
