A bug making "ya ya ya" sounds, a toad with an "emoticon" face...how many creatures from the dinosaur era have you missed?

Dinosaurs lived from the Triassic period about 245 million years ago to the end of the Cretaceous period 65 million years ago. This is a long period of time, also known as the Age of Reptiles. In addition to the dominant species of dinosaurs, many other types of creatures lived in the Earth's ecosystem during this period, and they witnessed the rise and fall of dinosaurs. So what species existed in this era? Let's talk about it today.

01. What mammals existed during the age of dinosaurs?

Let's first talk about the mammals of that period. For example, the horses, cows, sheep, pigs, dogs and rabbits we see today, their ancestors all lived with dinosaurs (mammals first appeared in the late Triassic to early Jurassic).

Of course, your ancestors were also included, but at that time, we looked a bit... Look at the picture, please pay attention to the size!!!

Purgatorius

02. Things from the same era as dinosaurs

Next are some things that lived at the same time as the dinosaurs.

Reconstruction of the True Thief Beast (two beasts, the God and the Immortal, from the Jurassic period of China), 160 million years ago, these names are really intoxicating. (It seems that whoever discovered it first named it, and there is also a bug called "Yiyayiyayiya")

Megaconus, or "big-toothed," plodded rather than hopped, and got its name from its distinctive teeth. The fossil was found in volcanic ash preserved in a freshwater lake in Inner Mongolia. The animal is thought to be a close relative of mammals, with some mammal-like traits, but other traits more commonly seen in reptiles.

Of course, in addition to the above-mentioned magical ancient creatures, we actually have some living fossils. For example, the platypus is a very ancient creature and one of the most primitive mammals.

The North American opossum , Didelphis virginiana, is one of the earliest marsupial (kangaroo) mammals.

And this guy is even tougher than the dinosaurs, the Indian purple frog (Nasikabatrachus sahyadrensis) , which coexisted with the dinosaurs for 70 million years, surviving the famous catastrophe that wiped out the dinosaurs and entering its modern stage to the amazement of scientists.

As for insects, I won’t mention them, such as the indestructible cockroaches…

03. What other aquatic organisms are there?

This is even more true for aquatic organisms. For example, this thing, when I was a child, I always thought it was the legendary trilobite. Horseshoe crabs are ancient creatures that appeared in the Devonian period 350 million years ago.

Frilled shark. Probably lived in the Jurassic period (95 million years ago and 380 million years ago)

Jurassic shrimp has 10 legs and its name suggests the time period.

Nautilus , 500 million years old

This shows that there were many creatures living in the dinosaur era.
