15 NATURE FACTS THAT MIGHT JUST BLOW YOUR MIND

11. SHARKS WERE AROUND BEFORE DINOSAURS
Long before dinosaurs, sharks were swimming in our oceans. In fact, sharks have been on this planet for over 400 million years, while dinosaurs lived in the Mesozoic era –– between about 245 and 66 million years ago.

Unlike dinosaurs, a shark’s skeleton is made up entirely of cartilage instead of bone, so they don’t leave behind fossils like other animals. However, many fossilized shark teeth have been found throughout the years.

I like the way @best  tells us the strange facts of nature.
How come we didn't know some facts or hadn't thought about them?!🤯💯
Wonders about nature don't end🏜...
