Abstract in brief

  • A new tyrannosaur species discovered in Montana provides evidence that some dinosaurs, like these tyrannosaurs, evolved gradually through a process called anagenesis, where one species smoothly transitions into another without a sudden change.
  • Phylogenetic analysis shows this new species is closely related to Daspletosaurus torosus, and the evidence suggests they might represent a single, evolving lineage rather than separate species over time.
  • The fossil details also reveal that this tyrannosaur likely had a crocodile-like facial sensory system with highly sensitive, scaly skin, and a lower jaw with neurovascular features similar to birds, indicating advanced tactile and sensory capabilities.

@nidohime Reception of this hypothesis has been varied - some sectors of the research community support it as a likely model, others are sceptical. The paper "A new tyrannosaur with evidence for anagenesis and crocodile-like facial sensory system" is open source if you are interested.
