Researchers report the identification of a new dinosaur species based on fossil material that has been overlooked for more than a century. The discovery is made from a fragment that forms part of a dinosaur skull, rather than from a newly excavated specimen.

According to both outlets, the relevant fossil piece was acquired by the Natural History Museum in 1924 and has remained in the museum’s collections since then. The reports emphasize that the specimen’s scientific value was not recognized until now, when researchers re-examine existing holdings. While both accounts focus on the long period during which the fossil was not used for a formal discovery, they do not provide additional details in the supplied text about the dinosaur’s name, age, location of origin, or the methods used to determine it as a distinct species.
