Not dinosaurs, these animals that inhabited planet Earth first. The shapes are so unique, what do they look like?
During this time, dinosaurs are widely known as one of the most popular ancient animals and the earliest living in the world, which is about 230 million years ago, to be precise in the Triassic period.
But you also have to know that there are still many other animal species that had inhabited this earth before the dinosaurs came, you know.
Just like the newer species, these ancient animals also had diverse characteristics and different habitats.
In fact, some of them are classified as the largest animals in their category.
In addition to ancient, the following animals also have a physical appearance that is certainly unique, as quoted from Kumparan. Come on, let's check one by one!
The shape of the animal that is estimated to have lived 600 million years ago based on this fossil finding has a symmetrical oval-shaped body.
The specimens found by scientists vary in size, from a few millimeters to about 1.4 meters.
This ancient animal was first discovered in South Australia in 1947 and has been widely studied by a number of scientists.
Astraspis is still related to several fish that also lived in other Ordovician times such as the South American Sacabambaspis and Australian Arandaspis.
Judging from the fossil, this fish has a length of about 20 centimeters with a moving tail covered in scales like small protective plates. Unlike other fish, aspiris do not have fins on the sides of the body.
Specimens obtained from North America have relatively large eyes and eight gill openings on each side.
This ancient fish species lived 450 million years ago.
Haikouichthys is about 2.5 centimeters long and has no jaws.
Its body structure is quite unique, in that it has a distinct head and tail with a prominent dorsal fin.
The Haikou fish fossil was found in Yunan, China and was clearly described in 1999.
Haikouichthys is known as the earliest fish on earth, as well as the most primitive vertebrate or vertebrate animal.
The size of Scutosaurus fossils that have been found ranges from 2.5 to 3 meters with a skull as large as 50 centimeters and has an armored body. Very tough, it seems.
Unlike other reptiles, the scutosaur's legs were under its body to support its massive body.
The gruesome visuals of the scutosaurus didn't make it a terrible predator, due to the fact that the scutosaurus was a slow, herbivorous reptile.
Based on the fossil remains found, jaekelopterus has a size of 2.3-2.6 meters and makes it the largest arthropod that ever existed.
The shape itself is similar to that of a lobster, except that its claws are embedded in its face and are smaller.
With its compound eyes, jaekelopterus has high visual acuity which makes it an apex predator.
This aquatic animal lived in the Devonian era about 390 million years ago and is dubbed the "sea scorpion" - however, research has found that jaekelopterus can live in fresh water.
Now you know, the unique animals that once existed on this earth, even far ahead of the dinosaurs that are so famous?
Ancient animals did have different characteristics from modern animals, but their appearance was not much different from those of today. Right?
