T rex didn’t become an 8-ton giant overnight: Scientists reveal how long the apex predator took to grow
A group of researchers has estimated how long it took tyrannosaurus rex to reach its full size — and the time period is significantly longer than scientists previously believed.The dinosaur is believed to have been Earth's largest land predator. It may have taken around 40 years — not 30 — for it to reach its full size, according to the new study.The findings were published in the journal PeerJ. The growth trajectory "is more gradual than expect…
This was the kind of animal you were better off befriending while still young: the Tyrannosaurus rex took perhaps 35 to 40 years to reach its full adult size. In other words, it took nearly four decades to become an 8-ton giant. Before that, during the first part of its life, it was probably just another predator—efficient, certainly, but with competition. For experts on this creature, which disappeared along with the other dinosaurs 66 million …
In an in-depth analysis of the growth of 17 specimens of tyrannosaurs, paleontologists suggest that these large carnivores reached their adult size only at the age of 40, instead of 25 years as previously estimated. This slower growth time would probably have allowed them to impose long-term superpredators at the end of the Cretaceous, notably by occupying several ecological niches throughout their lives. Tyrannosaurus rex is one of the non-dino…
T. rex Didn’t Reach Full-Size Until Age 40 - New Study
Eddie Gonzales Jr. – MessageToEagle.com – For decades, scientists have been counting annual growth rings, similar to tree rings, found inside fossilized leg bones of Tyrannosaurus rex to estimate how old the giant carnivores were when they died and how quickly they grew to adulthood. Juvenile Tyrannosaurus rex were fleet-footed with knife-like teeth, dominating the […]
