PaleoGuy is a contributor on Topix Dinosaur Forum. He arrived in January 2014 and quickly began contributing, while ignoring many spammers on the forum. He took a hard-headed stance against creationism, much like most of the forum's current and former users. He contributed to the forum somewhat infrequently, though the bulk of his posts were of good quality.

His contributions had been applauded by some Imperial Palace users, who had invited him to IP. However, because the process of registering on IP is complicated and lengthy, he had given up. He still made contributory comments on Topix, although as few contributors remained on the forum, his posts were largely ignored.

PaleoGuy has not been seen on Topix Dinosaur Forum since July 2014, most likely due to troll activity.
