These 7 Animals Survived What Dinosaurs Couldn’t


Have you ever wondered what life was like when dinosaurs roamed the earth? Well, it turns out, there are vestiges of that life everywhere today.

The Mesozoic era brought forth more than 180 million years of dinosaurs until their extinction 65 million years ago. About 50 percent of the planet’s animal and plant life survived the Cretaceous-Tertiary mass extinction, also known as the K/T boundary.

Here are some of the animals whose ancestors walked (or swam) alongside dinosaurs:


The platypus is one of the few monotremes still in existence today. The egg-laying mammal was only recently discovered to have lived during the Jurassic period. After analyzing a Teinolophos jawbone in 2008, University of Texas paleontologist Tim Rowe discovered that platypuses dated back as far as 122 million years ago.

Platypuses are one of only two mammalian species that lay eggs, the other being echidnas, or spiny anteaters.

Where you can see them: Platypuses live only in eastern Australia and Tasmania; reclusive, nocturnal echidnas live all over Australia.


You already know roaches never die. These insects were one of the most dominant species during the Carboniferous period — which took place about 360 million years ago (or 112 million years before the dinosaurs) — and they were about twice as big as their current form. They made it through the mysterious “Great Dying” period between the Permian and Triassic periods and were there to greet the first dinosaurs 240 million years ago.

Where you can see them: everywhere.

Horseshoe Crabs

People have called horseshoe crabs “living fossils” for years, but they’re actually arthropods similar to scorpions and spiders. Horseshoe crabs have evolved more slowly than other animals, but they’ve become one of nature’s most-enduring organisms, —> Read More
