Fossil, Geology, and Science Video Collections 27MAR2020

 Fossil, Geology, and Science Video Collections

Given the current troubles that have much of this world in lock-down in
their homes,
I have collected the URLs for different collections of geology, fossils,
and general
science videos for the Houston Gem and Mineral Society. To share them with a
wider audience I have posted the list below.
