Shawn and his wife live remotely in a 880-square-foot cabin along with their three dogs. They implemented many of the things they learned from the internet and trial and error. They have been helped by so many contributors over the years and desire to now return the favor to other Canadian Homsteading readers. They heat with a woodstove and cut firewood by hand from their 11 acres. They went back to the land and are essentially do-it-yourself people.
Recently it was identified in Argentina a new species, Ingentia prima. And it turned to upsize down the hypothesis about dinosaur evolution.
Researchers see now the prehistoric creatures in a new light. In the first place, they thought their existence developed 25 million years later. “Before this discovery, gigantism was considered to have emerged during the Jurassic period. But Ingentia prima lived at the end of the Triassic, between 210 and 205 million years ago”. Ingentia prima means “first huge”. The mysterious species broke the science grounds.
The research took place in western Argentina. In Balde de Leyes they could also find other prehistoric species, as mice, turtles, and iguana.
Fast track to growth
Gigantism was an adaptation, very useful, especially for herbivores. Herbivores had no other way to defend themselves. They could only make use of their considerable proportions.
Genetics developed a mechanism named cyclic growth. The adaptation permits growing, again and again, in several phases. Ingentia prima was a four-legged herbivore that had more than 1.8 tonnes and measured more than 3 meters. It had also a special bone construction, according to Apaldetti. “These pneumatic cavities indicate that this new species had highly developed air sacs”. This feature ”also helped it to keep its body cool despite its large size”.
But in the Cretaceous period, there were dinosaurs weighing more. The herbivore dinosaur was the first in the prehistory of such dimension. “This finding gives a new look at the magnitude of the evolutionary explosion that the dinosaurs had.” The quote belongs to Diego Pol, an Argentinian paleontologist.Ingentia prima paved the way toward gigantism.
”This evolutionary explosion was so great that it explains the success the dinosaurs had during the rest of their era,” said Diego Pol.
