In 1988, controversial paleontologist Robert Bakker continued to advise the filmmakers of Jurassic Park, giving the world hope, according tomedia CNET. He suggests the existence of a previously misclassified tyrannosaur species called nanotyrannus, which is slightly larger than the maroon. More studies have been conducted to challenge this claim since 2001. A new study published Wednesday appears to have dashed the hopes of anyone who believes the species exists. Scientists now say it is more likely that the tyrannosaurs are just “teenage” tyrannosaurs.
The study details how the team cut fossil bone samples into thin sheets so that light passes through, then gazed at them with a high-fold microscope to count their rings – just as you might have calculated the wheel on the tree’s cross-section. By measuring the size of the vascular openings, the researchers were able to determine that the dinosaur individuals they studied were still growing at a rapid rate at the time of death. The study, led by Holly Woodward of Oklahoma State University, was published in the journal Science Advances.
“The cool thing about bone fossils is that an entire bone leaves the fossil even to a microscopic size,” Woodward told AFP. “We can infer the rate of growth, age (and) maturity … Everyone loves the Tyrannosaurus rex, but we don’t know much about how it grew up. “
Woodward said the study added to scientific knowledge about dinosaurs from birth to adulthood, but it was difficult to gain more insight. There are only five to seven fossils of tyrannosaurs known in the world, some of which are private collections that researchers cannot obtain.
