In Depth
Bonnerichthys is a genus of very large filter feeding fish that lived during the Late Cretaceous. By becoming a filter feeder of plankton, Bonnerichthys had access to a near limitless supply of food, while expending very little energy in gathering it, meaning that more calories could go into building and maintaining a large body size.
Relative genera to Bonnerichthys include Rhinconichthys and Leedsichthys.
