The discovery of a new species of elasmosaur in North America has added to the continent’s impressive roster of dinosaur species. Named Traskasaura sandrae, this unique genus of elasmosaur was recently described in a study published in the Journal of Systematic Palaeontology. Measuring nearly 40 feet long, this marine reptile had heavy, sharp teeth suited for crushing prey and a mix of primitive and evolved traits unlike any other elasmosaur.
With 36 well-preserved cervical vertebrae and 50 neck bones, Traskasaura had an exceptionally long neck. While its behavior remains largely unknown, the unique features of its bones suggest it was a strong downward swimmer, possibly hunting prey from above. Its robust teeth could have been used to crush the shells of ammonites, a common prey in the region.
The fossils of Traskasaura were first discovered in 1988 along the Puntledge River on Vancouver Island. Additional fossils, including an isolated right humerus and a juvenile skeleton, have been recovered since then. These fossils were officially designated as the provincial fossil emblem of British Columbia following a province-wide public poll in 2018.
According to paleontologist F. Robin O’Keefe, the strange mixture of characteristics in Traskasaura led to confusion in identifying the species. A new, excellently preserved partial skeleton allowed researchers to further understand the morphology of the Puntledge River elasmosaur, leading to the naming of this new genus and species.
With the discovery of Traskasaura sandrae, the Pacific Northwest now has its own Mesozoic reptile to call its own, adding to the rich paleontological history of North America.
The Pacific Northwest is famous for its rich marine life today, but did you know that this region was once home to strange and wonderful marine reptiles in the Age of Dinosaurs? During this ancient time, creatures like plesiosaurs, ichthyosaurs, and mosasaurs roamed the waters of what is now known as Washington, Oregon, and British Columbia.
Plesiosaurs were long-necked marine reptiles with four flippers that allowed them to gracefully navigate the oceans. These creatures ranged in size from small, agile species to massive predators like the Elasmosaurus, which could grow up to 46 feet in length. Their streamlined bodies and powerful jaws made them formidable hunters in the prehistoric seas.
Ichthyosaurs, on the other hand, were dolphin-like reptiles with sleek bodies and large eyes adapted for hunting in low light conditions. These marine reptiles were incredibly diverse, with species ranging from small, fish-eating forms to giant apex predators like the Shastasaurus, which could reach lengths of over 60 feet. Ichthyosaurs were some of the fastest swimmers of their time, relying on their speed and agility to catch prey.
Mosasaurs were another group of marine reptiles that thrived in the Pacific Northwest during the Age of Dinosaurs. These creatures were more closely related to modern-day lizards and snakes than to dinosaurs, but they ruled the seas with their powerful jaws filled with sharp teeth. Mosasaurs like the Tylosaurus were top predators, preying on fish, squid, and even other marine reptiles.
The fossil record in the Pacific Northwest provides valuable insights into the diversity and evolution of marine reptiles during the Mesozoic Era. Scientists have unearthed numerous specimens of plesiosaurs, ichthyosaurs, and mosasaurs, shedding light on their anatomy, behavior, and ecological roles. These discoveries have helped researchers piece together the complex puzzle of life in the ancient oceans.
Today, the legacy of these marine reptiles lives on in the form of fossils, museum exhibits, and scientific research. Visitors to the Pacific Northwest can explore the region’s prehistoric past by visiting museums, fossil sites, and paleontological digs. By learning about the strange and wonderful marine reptiles that once inhabited these waters, we can gain a greater appreciation for the rich natural history of this unique and diverse region.
