Biggest extinct animals in the world. The chelicerates which includes spiders, mites and scorpions, and other similar creatures. The tiny vaquita porpoise, which is less than 30 left in the world, will likely go extinct in the next few years. Just after the dinosaurs went extinct around 60 million years ago, a massive snake called the titanoboa took their place as the biggest, baddest predator on earth.

But some other extinct animals were longer, if not heavier than blue whales, most being dinosaurs. The longest dinosaur called the seismosaurus measured between 130 and 170 feet in length and is arguably one of the longest animals. Join us as we travel back in time to discover the sad stories of eight of these incredible creatures… eight extinct animals.

Megafauna can be found on every continent and in every country. Bigger still is the fernandina galápagos tortoise, which was thought to be extinct for over 100 years. The biggest impact on bird population has been caused by degradation and loss of habitat, with collectors’ activities and invasive species following closely.

Although this event has been ongoing for the past 10,000 years or so—since the last ice age, to be exact—the mass extinction has been accelerating at a dizzying pace. Hiding in the undergrowth of african tropical forests, goliath beetles take the top spot as the heaviest insect in the world! Megafauna are simply big animals.

Areas off the california coast hold the densest population. The largest animal that ever lived is the blue whale. Megalodon is by far the biggest mackerel shark and largest shark known.

A world with no action and adventure. A classic example of what evolutionary biologists call insular gigantism, deinogalerix grew to plus sizes after its ancestors were stranded on a group of islands off the european coast, blessed with a) lots of vegetation and b) virtually no natural predators. Megalodon means “big, mighty” in ancient greek.
