In the mist of a primeval Triassic Tropic there once roamed the Mighty Jacosauros Costaricus. In the DNA metamorphosis that had been occurring during this period around 250 million years ago, there was one specific form of amphibious reptilian that had developed Thecodent socketed teeth. The majority of the Archosaurmorpha were destroyed in a major extinction event. I propose that, off of the shore of Jaco Costa Rica on a low lying sea shelf there was once a low lying lake bed during the Pangaea era. This is where the mighty Jacosaurs roamed.
