JAEKEOPTERUS



Sometimes I like to revel in the oldest prehistoric animals, put aside the great saurian to which we are accustomed to seeing and who are better known and delve me at the beginning of life, dive into the origin of evolution. When existing evolutionary branches were more diverse and where we find primitive animals and, in a way, awaken our imagination.

The Jaekelopterus is a good example. If we read a book of science fiction, books describing other worlds and invented creatures living in it, we could find a Jaekeloptero swimming in its waters.

Brief description of the animal: this prehistoric animal, it is the order of the eurypterids, namely Scorpions sea. Among all species of these ancient scorpions, the bigger the Jaekelopterus.

Its dimensions are tremendous, we are talking about more than 2.5 meters long (just imagine a scorpion 2.5 meters long (82 ft.)  coming through the door of the room by going directly to you ... scares eh?) So great was that it is considered a predator who held one of the highest positions in the food chain....
How they hunted?
Together with those dimensions, hunting is the most amazing of all. The Jaekelopterus had two pincers of no less than about 50 cm  (16 ft.) in two of its appendages that could extend to grab its prey tightly. Close and personal with a rapid expansion of its appendices remained motionless at predated while it was eating it.

This last detail makes us think one thing. We have said that could reach 2.5 meters long (82 ft.). But when his paws and claws extended, the length of this increased to one meter, reaching measuring 3.5 meters long (115 ft.).

However, no one seems to ensure that it was a true predator, and it seems that this animal could get most of their food from the carrion of other dead animals.

As is understood by the name, this animal was aquatic. But it is thought that did not live in seas, but in swamps, rivers, etc ...
He lived in the Devonian, 390 million years ago, when many of the mainland were still together.

Finally, these animals are a bit in no man's land. It is not known exactly whether they are really related to scorpions, with arachnids or the horseshoe crab.

CAMARASAURUS.


As its name suggests, (Camarasaurus) comes from camera .... but not the camera taking pictures. It refers to the camera as room as hollow, or internal and covered space. This refers to two bone peculiarities: the vertebrae, though robust, are quite hollow inside, and on the other hand, the skull was square and its huge nostrilsgiving the sense of having a very hollow or empty skull.



But what was a Camarasaurus?

It was a herbivore, a great vegetarian 18 meters long and 18 tons. It was a long sauropod like Diplodocus or Argentinosaurus. It was not as big as them, even for a sauropod, had a rather short neck and tail. However, the body was very strong, so experts estimate that could reach 18 tons.
It lived 150 million years ago in what is now North America.

Another curiosity is that when paleontologists mounted their bones, found a lump of hip bones. It has been speculated about this, and apparently could be that it was another brain, hip, not in the head ... I repeat: another brain in the hip. Finally, another brain or nerve plexus great about it .... still no full consensus.

The other curiosity we can emphasize is the domed shape of its skull. The experts believe that this will served as a sounding board to create a sound effect that could be used to communicate with other Camarasaurus. I imagine a Camarasaurus, warning of the attack by a group of Allosaurus, with a sort of nasal sound, similar to today's large ships when they enter port.

More things:

  • The Camarasaurus could not be applied on its hind legs.
  • Its front legs have claws capable of giving a good blow to their attackers.
  • Analyzed his teeth, thought to eat vegetables harder than Diplodocus.
  • It lived in the Jurassic.
  • To facilitate digestion, it could swallow stones, as is currently done some birds and other herbivores.
