In the context of modern paleontology, which studies the remains of ancient creatures and cultures that once existed on Earth long before human arrival and development, many questions are devoted to aspects of the so-called “middle” evolution – in other words, to those periods of evolution of living creatures, when they had not yet become as we know them. Today's new discovery of paleontologists from the Geological University of Virginia only confirms that there are obviously more questions than answers – because the specialists managed to find and identify a rather interesting ancestor of the very Tyrannosaurus rex that was once the most ferocious and dominant predator on the planet.
As for the remains themselves, according to preliminary research data, they belong to the so-called Suskityrannus hazelae, which was the very pre-evolutionary stage of the birth of a tyrannosaur – the remains were preserved quite well, despite the fact that initially some of them were found in 1998 and contained in not very tolerable conditions. According to a computer model built by specialists, this subspecies of an early tyrannosaur who lived in the Cretaceous period about 92 million years ago – in its middle, more precisely, was small enough, with an average height of 3 feet to the hips and about 9 feet in full growth.
In addition, drawing attention to the state of bone tissue, the scientists concluded that it was these remains that belonged to a rather young sample for about three years. It is worth noting the fact that the sample also clearly indicates that one of the most dynamically developed spheres of the structure of a tyrannosaur was the head, which gradually lengthened.
The skeleton itself has not been fully preserved and is represented only by scattered fragments – but this in no way prevented the researchers, who eventually recreated the early Suskityrannus hazelae in their full splendor. Thus, the presented study becomes one of the most valuable and interesting, since it sheds light on many particular evolutionary factors in the development of dinosaurs, in particular, the royal tyrannosaur.
