New study revises T. rex growth timeline, reached full size by 35–40 years

A study of 17 Tyrannosaurus rex fossils using polarized light reveals growth rings showing they grew slowly, not reaching a maximum size of about 8 tons until about 35–40 years old. Growth rings capture only the last 10–20 years of life, but by combining data across ages researchers reconstructed year-by-year growth, finding more variability and suggesting possible taxonomic differences such as Nanotyrannus; the findings revise the dinosaur’s growth timeline and how it occupied various ecological niches.

"Nanotyrannus: Real Dinosaur or Young T. rex? The Significance of the Debate"

The debate over whether "Nanotyrannus lancensis" was a unique species or a young T. rex continues to stir controversy, with some arguing that the fossils attributed to "Nanotyrannus" are simply those of adolescent T. rex. Despite decades of debate and multiple studies, the consensus among tyrannosaur experts is that there's no solid case for "Nanotyrannus." The controversy has inflated the prices of tyrannosaur fossils at auctions, with a recent skeleton listed for sale at $20 million, reigniting the debate. However, the scientific community remains unconvinced, and the focus on "Nanotyrannus" is seen as a distraction from more meaningful paleontological research and conservation efforts.

"T. rex: New Study Challenges Previous Understanding"

A new study suggests that miniature versions of the Tyrannosaurus rex may actually be a distinct species called Nanotyrannus, with researchers from the University of Bath and University of Chicago finding evidence that the smaller dinosaurs were likely almost full size and had over 150 distinct characteristics from their larger counterparts. This contradicts a 2020 study and has sparked a renewed debate in the paleontology community, with some scientists welcoming the new perspective while others remain unconvinced.

"Debate Intensifies Over T. Rex Identity Amid New Fossil Controversy"

A new study by researchers from the University of Bath and University of Chicago suggests that what were previously thought to be juvenile Tyrannosaurus rex specimens might actually be a distinct species, potentially called Nanotyrannus. The study, published in the journal of Fossil Studies, analyzed growth rings in fossils and found evidence of slower growth rates, as well as over 150 distinct anatomical features, such as narrower snouts and longer arms, differentiating them from T. rex. This challenges previous beliefs and suggests that the smaller dinosaurs were not just young T. rexes but a separate species that relied on speed rather than size and strength. The debate continues as not all scientists are convinced by the new findings.

"Debate Reignites as Studies Clash Over Tiny Tyrannosaurs' True Identity"

A new study published in the journal Fossil Studies claims that certain controversial dinosaur fossils belong to Nanotyrannus lancensis, not juvenile Tyrannosaurus rex, based on growth ring analysis and anatomical reconstruction. However, the study has been met with skepticism from other experts who argue that the differences observed can be attributed to growth variation in tyrannosaurs, and that the key fossils needed to definitively settle the debate have not yet been discovered. The debate over whether Nanotyrannus is a distinct species or simply a young T. rex continues, with some paleontologists open to the possibility of a second species in the Tyrannosaurus genus but calling for more convincing evidence.
