EngagementModerate engagement

Participants reference specific aspects like mortality patterns and age-related survival, suggesting moderate engagement.

ImpactModerate impact

The discussions highlight the significance of the study for paleontology and dinosaur biology, but the influence appears moderate.

Abstract in brief

The study examines the population structures of four North American tyrannosaurs, showing a pattern where many juveniles survive, but mortality increases during middle age and near the species' maximum lifespan.
This age-specific mortality pattern resembles those seen in modern long-lived animals like birds and mammals, and may be influenced by factors such as predation and reproductive behavior.
The findings help explain why juvenile tyrannosaurs are rarely found in museum collections, as they likely had high survival rates early on but faced increased risks later in life.

@Antrodemus @Goji_Saurus @TM9380 @AzzopardiDilyn @MiloGaillard3 @Juanyudocus In the first source I showed you it was not among the asymptotic ones, and in this source it's said to be 22 years old so not as young as Stan but not as old as Sue or Scotty. And it does not show mature EFS, unlike the 50 year old Giganotosaurus https://t.co/d5u1vdln1H
