EngagementModerate engagement

Many posts reference specific details about the species and its context, indicating a moderate depth of engagement with the research.

ImpactHigh impact

Users widely regard the findings as having significant implications for our understanding of troodontid evolution and biology.

Abstract in brief

  • Researchers describe a new troodontid species, Urbacodon norelli, found in the Upper Cretaceous Iren Dabasu Formation in China, based on a partial jaw and teeth.
  • This species is unique from other troodontids due to specific features like paired dentary foramina and a lack of a chin, and it is related to another species, U. itemirensis, confirming a common ancestry.
  • The study reveals an alternating tooth replacement pattern in U. norelli and suggests that rapid changes during tooth development prevented the formation of interdental plates, enhancing understanding of troodontid feeding ecology and tooth biology.

Urbacodon norelli is a small basal troodontine known from teeth and a right dentary found at the late Cenomanian-Turonian Iren Dabasu Formation, where we also have a few postcranial fragment belonging to a Saurornithoides-sized taxon. https://t.co/rba5lyz3z5 https://t.co/89CnSpot9w
