Most Unique Extinct Species

A recent study showed that around a million species are currently at risk for extinction. While a huge tragedy, the fact is a ton of species have already vanished from the world, either through natural selection or human activity. Here are some of the most unique examples:

Giant lemur

Fossils were found in the 1860’s, showing that this lemur from Madagascar could grow as large as a gorilla. It behaved like lemurs we know today, and could move through trees very quickly. It also probably didn’t see well during the day. If you ran into one of these in the past, you wouldn’t have to fear: they ate leaves.

Whorl sharks

Living over 300 million years ago, these ancient sharks would be terrifying to behold. Fossils reveal a strange tooth structure like a circular saw in the lower jaw, though we aren’t quite sure where it was placed. Regardless of is exact location, it most likely did a lot of damage to any prey.

Cooksonia plant

Experts believe this extinct species may have been one of the first plants ever. It lived in water over 400 million years ago, and may have even grown submerged in water. On the end of each stem you would find spores, but fossils reveal the cooksonia didn’t have leaves or a root system. Those parts might also have just not fossilized, but we’ll likely never know.


This plant existed during the time of ancient Greeks and Romans. It grew especially well in the city of Cyrene and bolstered its trade. Why was this plant so special? At least one historian believes it was used as birth control. Silphium eventually went extinct from overuse. According to Legend, Emperor Nero got the last stalk, but he immediately ate it.


Indiana Jones would faint if he ever time-traveled and saw one of these monsters. Found in swampy, hot jungles, these giant snakes could grow up to 50-feet long and weigh over 2,500 pounds. They could eat just about anything, so a human man would have been no challenge. We’re lucky our timelines didn’t overlap.
