Why is Troodon no Longer a Dinosaur?
Troodon was once classified as a dinosaur, but recent research has led to its reclassification as a member of the group known as paravians. Paravians include some of the closest relatives of dinosaurs, such as birds. While Troodon shares many similarities with dinosaurs, such as feathers and three-toed feet, it also possesses certain characteristics that distinguish it from true dinosaurs.
One key difference between Troodon and dinosaurs is its wrist structure. Dinosaurs typically have a semi-lunate carpal bone in their wrists, but Troodon lacks this bone. Additionally, the ankle joint of Troodon is structured differently from that of dinosaurs.
Based on these and other anatomical differences, paleontologists now classify Troodon as a paravian. This reclassification highlights the complex and ever-evolving nature of scientific classification and the importance of ongoing research in shaping our understanding of the natural world.
