Fun Facts about dinosaurs posted multiple times per week. Formerly DailyDinoFacts on that other app. Paleo volunteer trying to break into the world of collaborating on research papers. Dino Fact requests encouraged - just DM me!
In dinos, you can approximate age based on Lines of Arrested Growth (LAGs) mostly researched in load-bearing bones. They look like tree rings. Notably, when an animal is growing, the rings are wide (showing a period of growth). At adulthood, the rings become small and tightly packed (slowed growth).

The problem with Nanotyrannus is that the remains people argue over aren't mature animals, leading many researchers to conclude they're just young T.rex (even if that idea also presented some sticky problems.) To finally settle it, folks said, you'd need to find a Nanotyrannus adult.
They did.
They did.
