Hey! Today, we go back 300 million years, to a time before dinosaurs. We will meet the first reptiles, and killer insects. Wwwwwwhhhhhhhoooooossssssssssssssshhhhhhhhhhhhhhhhhhh! Ah, here we are. Now, these lizards here are Petrolacosaurus. they are the first reptiles, facing a whole new world-full of whole new dangers. Remember Brontoscorpio and Pterygotus? Well, they’ve returned as giant insects like-whoa! This!

Eagle-no! Dragonfly!
It’s called Meganura, and it’s as large as an eagle. But this is just one of four kinds of giant insects we should see. Look! Mesothelae! otherwise known as giant spiders!

Along came a giant spider....
She’s HUGE! About as large as a human head! If she were to be alive 300 million years later, she would hunt cats! But 2 down 2 to see! Meanwhile, let’s see what evolution did to cause reptiles.

Ah, amphibians. They then evolved into reptiles.
Cool, eh? Aha! Pulmonoscorpius!

Sting!
One more giant creepy crawlie too see! And here he comes! Arthropleura!

that's one big millepede!
And that’s it for today! Next time, we explore the world of the nastiest dinosaurs ever. Next time, we explore T-rex and raptors!
