A significant discovery has been made in Colorado’s Dry Mesa Dinosaur Quarry, where paleontologists have unearthed a new specimen of Haplocanthosaurus, an intermediate sauropod dinosaur from the Late Jurassic period, approximately 155 to 152 million years ago. This new finding contributes valuable insight into the anatomy and evolutionary position of the enigmatic genus, which remains less understood compared to other Morrison Formation dinosaurs like Apatosaurus and Diplodocus. Details of the New Specimen According to a study published in The Anatomical Record, the specimen includes three anterior dorsal vertebrae, four posterior dorsal vertebrae, and a right tibia. Researchers identified it by distinct anatomical features such as dorsally angled transverse processes and a broad distal tibia. Dr. Mathew Wedel, a paleontologist at Western University of Health Sciences, stated that the new specimen is the geologically youngest example of Haplocanthosaurus discovered on the Colorado Plateau. Haplocanthosaurus and Its Significance Haplocanthosaurus is considered a rare genus, known from only 11 specimens compared to the numerous fossils of other Morrison Formation sauropods. Dr. Wedel and his team explained that crucial …
