One Minute Old Fossils

A fossil is the remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock. Fossils Tell of Long Ago, the story read to the first graders of Grayson County Schools this month, explains the process of fossilization and the varying types of fossils that are formed. From tracks of dinosaurs to imprints of ferns, frozen woolly mammoths, bryozoans, cephalopods and brachiopods, fossils tell us of the past.

BRDC brought examples of fossils to the classroom for the students to explore and investigate. The sharks teeth were the biggest hit. The difference between a mold and cast fossil was explained and then each student was given a chunk of clay to make their own mold fossil using various materials.
