Coconventosaurus ingens

***Coconventosaurus ingens*** is an original extinct species designed and collaborated by User:GurgiFan57. It lived in what is now North America during the Maastrichtian, from 71 million to 66 million years ago, and was the last and the largest carcharodontosaurs to have ever lived.

## Appearance and anatomy

*Coconventosaurus ingens* was a larger relative of the slightly smaller *Giganotosaurus* of Argentina during the Cenomanian, with the length of 15.5 meters (50.9 feet) long, the height of 5.5 meters (18 feet) tall, and a weight of 9 tons (8,165 kilograms). Unlike  *Giganotosaurus*, *Coconventosaurus ingens* had large crests running from the top of its brow and down half of the skull, making its head look very similar to that of the fictional *Indominus rex*. On its back was a row of spines, beginning at the neck and running down the back until its hip region, where a hump-like collection of spines abruptly rises and then lowers back into the low spines and continues to the end of its tail. The teeth of the animal were quite similar to those of a crocodilian, and may have unevenly jutted out of its mouth, but this is disputed. *Coconventosaurus ingens* is thought to have been capable of running as fast as 30 miles (48 kilometers) per hour, despite its massive size.

## Behavior and ecology

*Coconventosaurus ingens* lived in various forested and open environments at the end of the Cretaceous period, having an apex predatory ecological niche and being one of the largest carnivorous dinosaurs of its time in North America, being one of the main competitors of *Tyrannosaurus rex*. As one fossil of *Moros kyebangensis* was discovered near the much larger fossilized skeleton of ***Coconventosaurus ingens***, it was once thought to have hunted *Moros kyebangensis*, but in 2015, paleontologists had found no bite marks or other injuries associated with any predators, so it is thought that they both simply died together.

### Diet

*Coconventosaurus ingens* was one of the top carnivores of North America at the end of the Cretaceous, and was adapted to feed on many of the large animals such as *Alamosaurus*, although it likely also stole kills from other predators such as *Tyrannosaurus*. It is thought to have had a symbiotic relationship with *Moros kyebangensis*, with the smaller *Moros kyebangensis* feasting on the fresh and rotting meat stuck in the larger animal's mouths.

### Behavior and intelligence

*Coconventosaurus ingens* is thought to have had an average intelligence among theropods, being most comparable to a modern ratite's in terms of its brain power.

### Reproduction

*Coconventosaurus ingens* probably mated for life, producing a clutch of over 9 eggs. Once hatched, the young were capable of standing, walking, and running within just hours, like some modern birds. The adults most likely taught their young how to find and find catch food, etc.

## Trivia

*Coconventosaurus ingens* was once thought to be a North American species of *Giganotosaurus*, but further analysis, including differences in skeletal structures and phylogenetic studies, proved that it was only a close relative of *Giganotosaurus* and was likely descended from a species of carcharodontosaurid from tens of millions of years earlier that had spread to North America from South America by island-hopping to different small islands while on the way, and these North American carcharodontosaurids survived competition from tyrannosaurs by being able to steal kills and hunting different prey from the tyrannosaurs.
