Living Fossil The earliest horseshoe crabs were found 450 million years ago as fossils in strata. Many think of them as crabs and crustaceans when in fact they are more related to spiders and scorpions. Under their enormous shell, their bodies also look more like those of spiders.

Living fossils, horseshoe crab fossils were found from 450 million years ago.

The coelacanth has been nicknamed a “living fossil”, because it originally was known only through fossils, long before the first discovery of a live specimen. The coelacanth is thought to have evolved into roughly its current form approximately 400 million years ago.

The primitive-looking coelacanth (pronounced SEEL-uh-kanth) was thought to have gone extinct with the dinosaurs 65 million years ago. But its discovery in 1938 by a South African museum curator on a local fishing trawler fascinated the world.

Basically unchanged for 300 million years (!), triops are truly a fascinating living fossil. They make a great short-lived pet for the curious observer and burgeoning biologist.

The horseshoe crab could hold the distinction of being the oldest animal species still in existence. Dating back to the Paleozoic era, the horseshoe crab existed on Earth before the dinosaurs and soldiered on through several mass extinction events. In 2008, a horseshoe crab fossil, the oldest in existence found so far, dated back to around 445 million years ago, according to a report by LiveScience.

Platypus.   Native to eastern Australia, the animal is the only surviving example of its family, Ornithorhynchidae. This group of animals is believed to have split from mammals some 166 million years ago.

Chevrotains | The 15 Cutest Living Fossils


Chevrotains, also known as mouse-deer, are small ungulates that make up the family Tragulidae, the only members of the infraorder Tragulina. The word chevrotain is French, and can be translated as "little goat".

Platypuses look like a mash up of otters, ducks, beavers, and a healthy dose of WTF. In reality, they’re creatures called monotremes, mammals that lay eggs. Platypuses wait for the eggs to hatch and then nurse their young with milk they excrete through pores in the skin. (Rather than you know, nipples) But it’s these basal mammalian characteristics make platypuses so interesting to scientists. Or maybe it’s the venom spurs on their feet? Whatevs. They’re cute when they smile, right?

Duck-Billed Platypuses

Maybe cute is't the word but this is an amazing creature. It looks a bit like it was made with spare parts.

Tuataras are kind of confusing because they look like lizards, but they’re not actually lizards. They are simply (and you’ll love this) “lizard-like” members of the order Rhynchocephalia. Tuataras have many features of primitive reptiles. For example, their lungs consist of a single chamber. They also have a third, or parietal eye, which is only visible in hatchlings.

Compared to other animals on this list, the mouse deer, better known as a chevrotain, is a relative newcomer. For a large mammal, however, it's relatively old. This animal is among the only survivors of a group of hoofed mammals that lived some 35 million years ago.

the lesser mouse-deer (also known as a kanchil). The lesser mouse-deer is native to parts of southeast Asia and is the world's smallest known hoofed mammal (adults weigh about four-and-a-half pounds).

Many living fossils still alive today have bizarre, eccentric traits that make them seem more like aliens than anything from this world.

<b>The term "living fossil" has been used to describe creatures that retain primitive features, have remained unchanged for millions of years, or are members of species-poor taxa.</b> Many of which, incidentally, are unbearably cute. Here are the most adorable of the lot presented in no particular order.

Amami Rabbits

They have elongated claws to dig, smaller ears to hide from predators and powerful muscles to dig.The Ryukyu rabbit is also nocturnal.

Another look at the goblin shark (Mitsukurina owstoni), a deep sea creature that's been sighted less that fifty times since its discovery. They're the only living representative of the family Mitsukurinidae. This thing is hideous.
