Coelophysis is a fanboy who began posting on the Topix Dinosaur Forum as a guest in Summer 2012 and posted semi-frequently on the Topix Dinosaur Forum until late 2014. His arrival was triggered by JMD, who extended him an invitation on another forum called Dinosaur Forum.
Coelophysis' posts are often plagued with misinformation and inaccurate statements. For example, he insisted that birds were not dinosaurs, but rather crocodilians. Because of this, many users, including Pinky And Ze Brain, Edaphosaurus, Lord of the Allosaurs, and Paleoworld-101, denounced him as a fanboy of John Ruben (A highly controversial paleontologist)
He is considered intolerable to most people on the Topix Dinosaur Forum, and his posts often pollute threads with false information and poor grammar. His most virulent phase of posting came shortly after his arrival in 2012, and afterwards his activity became less and less frequent. He popped up infrequently throughout 2013 and 2014, although he was usually ignored by other users because of his baseless, unscientific views. By late 2014, he had ceased posting altogether.
