Even despite dinosaurs died out millions of years ago, there room still some pets that have actually a link to those old beasts. From birds to alligators, these room five varieties that count dinosaurs as loved ones or neighbours!
The Tyrannosaurus rex was one of the largest, many fearsome animals ever come exist. Surely, anything regarded a T. Rex must be absolutely terrifying, right? Well, not quite! It turns out the king the the dinosaurs in reality shares a how amazing amount of DNA with modern-day day chickens! In fact, bird are frequently thought to it is in the only animals around this particular day that are straight descendants of dinosaurs. So following time friend visit a farm, remember, every those squawking chickens are actually the closestly living family member of the many incredible predator the world has ever known!
Although birds might be the only “modern" dinosaurs, there are plenty of animals around this particular day that re-publishing some outstanding connections with old animals. Because that example, dinosaurs are reptiles, a group that also includes turtles, crocodiles and also snakes! return they separation off pretty early on, dinosaurs and also these animals share typical ancestors. Modern-day crocodiles and also alligators are virtually unchanged native their old ancestors of the Cretaceous period (about 145–66 million year ago). That way that animals that were practically identical come the ones you have the right to see now existed alongside dinosaurs!
Like crocs and also 'gators, sea turtles room reptiles, just like dinosaurs. In fact, they’re often referred to as “cousins” of dinosaurs! They occurred alongside dinosaurs, emerging as a distinct kind of turtle around 110 million years ago. The seven species of sea turtle still roughly today all have old origins, however the most impressive turtle of all time is most likely the Archelon. Living around 80 million years ago, the Archelon was over 4 metres long and was nearly five metres vast from flipper to flipper. A grown man could easily fit within its shell. Today, the leatherback sea tortoise is its closest life relative.

Sharks have been around a long, long time. The faster sharks first emerged about 450 million year ago, with modern-day sharks first appearing roughly 100 million years ago. Today’s sharks room descended from relatives that swam together dinosaurs in primitive times. In fact, the biggest predator of every time to be a shark called a Megalodon. The lived simply after the dinosaurs, 23 million year ago, and also only walk extinct 2.6 million years ago. It might reach lengths of up to 20 metres and could weigh as much as 103 metric tonnes!
Crabs very first emerged in the Jurassic duration (about 200–146 million year ago), however they flourished in the Cretaceous period, just before dinosaurs go extinct. One of the most interesting varieties of crab alive during this time to be the Megaxantho Zogue, i m sorry was uncovered in Mexico.
