Understanding of the early evolution of tyrannosaurs is enhanced through embryo fossils found in Alberta, western Canada and the US state of Montana. (Julius Cosutoni interpretation)
For the first time, archaeologists have discovered dinosaur embryos, one in Alberta, western Canada and the other in the US state of Montana. Fossils of the young despot have been found before, but the youngest of them is 150 years old, three to four years old. The embryonic fossils are said to reflect “new light on how dinosaurs evolved from small to gigantic.”
One of the fossils found near Maureen, Alberta, is tiny toenails The Barthesur coffin Estimated age of 71.5 million years. The second is a small bone in the lower jaw. Daspletosaurus horneri It is found in Montana and is believed to be around 75 million years old.
“The discovery of the topic marked a breakthrough in our quest to understand how some of the most famous and unusual dinosaurs began their lives and grew to an enormous size. Brand strength, Second professor of study and doctoral student at the University of Alberta. “This is absolutely necessary; so far, no data point has been found that represents the starting point for dinosaur evolution.”

Improving the size theory of fossil dinosaurs.
Powers said There were two surprising results when studying the two fossils. For one thing, the teeth of young dinosaurs are different from the teeth of older people. They do not have the series available for teens and adults. Estimation of fetal size based on the second fossils. It appears to fit the theories developed by Canadian-American archaeologist Dale Russell that it does not have the benefit of embryonic fossils to function.
The chapters add that the findings “have a lot to teach researchers.”
This study was published by Greg Vanston, University of Alberta graduate. Special launch Canadian Journal of Geosciences Russell’s contribution to the field of archeology.
