BONC #8: Big Little Things

Here are some great examples of huge versions of species we know pretty well today...

This would be great at your Fourth of July clambake.... The freshwater sea scorpion Jaekelopterus rhenaniae probably lived approximately 390 million years ago was estimated to be over 8 feet long. The Jaekelopterus is a cousinof the Pterygotus, which you might recognize from your Giant Evolution timelines!

Or this thing, which isn't that old (11000 years). Doedicurus was the largest known glyptodontid. It was 5 ft tall and about 12 feet long. Dodicurus is very close to Glyptodon, which is also on the Timeline.

These next two animals should be pretty familiar to you.

How about an 8 foot long centipede? Meet the Arthropleura, the largest land invertebrate of all time! There are no fossils of its mouth so scientists have no idea what it ate!

Or a pretty dragonfly with a 3ft wingspan? Say hello to the Meganeura. They make scary movies about things like this! The Meganeura is the largest known flying insect.

And we’ve found one more, a favorite, the original giant shark. Megalodon would have swallowed Brody, Quint and Hooper in one bite.
