This is a redesign for the titular dinosaur from the Valley of Gwangi.
"Gwangisaurus Giganteus" meaning "Giant Gwangi Lizard" is a late-surviving carcharodontosaurid related to Mapusaurus.
Length: 13 meters (42.64 ft)
Weight: 6 metric tons (5.9 imperial tons)
Time: 4 MYA - present
Location: Mexico
Discovered: 1902
EDIT: because this is a fictional species, I used a combination of multiple skeletal diagrams for reference. It has the body of Giganotosaurus, the head of Acrocanthosaurus, and the arms of Neovenator.
