Description

The prionostracean, a new class of dinocaridids, devours a small vertebrate

This is the third geological period of Martian history. It started 470 million years ago and ended 390 million years ago. It was a great period of volcanic activity due to the opening of marineris valley, together with the warming climate, affect the ecosystem of the Boreal ocean, leading to the extinction of a large number of groups, most arthropods. After the event, the survivors began to recover ground, including new forms of Dinocarida.

The vertebrates took advantage of the gap and developed in different ways, like cartilaginous fish of the earth. at the same time, the ventulicolas evolved ways similar to fish with strong reinforcements and pseudo-jaws. The reefs are composed of crinoids and sponges.

Among the various new forms of Dinocarida, has evolved a class that possessed pliers to form a structure resembling a mouth. As well they developed a strange characteristic: fleshy fins. These fins allow them to move with greater versatility. in the future will represent an innovation for their descendants.

Meanwhile, in the sea of ​​hellas, because this is isolated from the Boreal ocean, this was not affected by climate change, which kept its intact ecosystem, but even changes. Most terrestrial organisms on Mars fall of species that inhabit the sea hellas. The main key in this waterbody animals are nectocarids, trilobites, and onicóforans. Began to emerge here the first autotrophic organisms.
