His contributions to palaeontology include synonymising the generaTroodon and Stenonychosaurus in 1987 (with the former name taking precedence)[7] and later reversing this in 2017.[8] He has also synonymised the ceratopsian taxon Rubeosaurus with Styracosaurus, the latter being the valid, senior synonym.[9]
Bird-dinosaur link
One of Currie's main interests has been the evolutionary link between modern birds and non-avian dinosaurs. The similarities between troodontids and birds in particular made him a major proponent of the theory that birds are descended from dinosaurs,[5] as did his finding that tyrannosaurids, along with many other non-avian theropod lineages, possessed furculae, a trait previously believed to be exclusive to birds and absent from non-avian dinosaurs.[10] As part of the joint China-Canada Dinosaur Project, he helped describe two of the first dinosaur specimens from the lagerstätten of the Liaoning in China that clearly showed feather impressions: Protarchaeopteryx[11][12] and Caudipteryx.[12] In contrast with the 1996 discovery of Sinosauropteryx, which only showed the impression of downy filaments, these were indisputably feathers.[5] This not only helped cement the theory that birds are descended from dinosaurs, but indicated that many dromaeosaurids were feathered.[13] He was later featured in numerous popular articles and documentaries.[citation needed]
Currie became increasingly sceptical of the orthodox belief that large carnivorousdinosaurs were solitary animals, but there was no evidence for his hypothesis that they may have hunted in packs. However, circumstantial evidence came when he tracked down a site mentioned by Barnum Brown that featured 12 specimens of Albertosaurus from various age groups.[15][16] Currie was also involved in the discovery of a bonebed which evidenced gregarious behaviour in the caenagnathoidAvimimus.[17] In 2023, Currie co-authored a paper describing evidence from the Danek Bonebed that Albertosaurus engaged in cannibalism.[18]
Phylogenetics
Currie has made important contributions to the study of phylogenetics. He contributed to a comprehensive revision of the phylogenetic relationships of ankylosaurid species in 2015.[19] He also reassessed the phylogenetic status of Nipponosaurus sachalinensis, discovering that it was much more basal among the Lambeosaurinae than palaeontologists had previously thought.[20] In 2022, he participated in a study that found Dineobellator to represent a novel dromaeosaurid outside any known clade of eudromaeosaurs.[21]
Currie's contributions to the study of dinosaur dentition include helping discover the first known instance of alveolar remodelling in dinosaurs[26] and revealing in a 2020 study that the dentition of Sinraptor bore extreme similarities to that of Allosaurus, further concluding that Sinraptor would likely have actively hunted medium-sized dinosaurs such as Jiangjunosaurus junggarensis.[27]
In 1997, Currie teamed up with Microsoft's Chief Technical Officer Nathan Myhrvold to create a computer model demonstrating that diplodocids could snap their tails like whips, and create small sonic booms.[33]
Currie helped rediscover the type localities of the Mongolian sauropods Nemegtosaurus mongoliensis and Opisthocoelicaudia skarzynskii in 2017; the location of both quarries had become unknown due to them being described several decades before and not having been studied for some time. The next year, he published a paper as the lead author in which he suggested the two taxa may represent the same species.[38]
As one of the world's foremost palaeontologists, Currie has been featured in many films, programs in radio and television, as well as in newspapers.[64] Apart from this, he has also been accessorial to many books:
