Parasaurolophus Titanii

Parasaurolophus Titanii is an extinct species of Hadrosaur part of the extinct genus, Parasaurolophus. Despite its species name, it was slightly smaller than Parasaurolophus walkeri of the Late Cretaceous. It was discovered in 2019 first as a fossil impression, with its skin colorations, fat, muscle, etc, preserved in stone, making it among the most accurate dinosaurs shown in restorations known to science, along with Psittacosaurus (an early bipedal ceratopsid which was mostly brown in color). Just like the modern day eastern duckbill and southern duckbill as well as other extinct Parasaurolophus species, it is believed that it may have had several functions: visual display for identifying species and sex, sound amplification for communication, and thermoregulation. Like all known Parasaurolophus species and like most Hadrosaurs, with the exception of Carnovorosaurus, it was a herbivore that mainly fed on ferns, cycads, leaves, and horsetails, but unlike most other Hadrosaur species of its time, it fed on grass, which first appeared in the Middle Cretaceous but was not very abundant during that time nor at the end of the Cretaceous period, but being a primitive browser and grazer meant that this species of Hadrosaur did survived the mass extinction, since grass weren't very much effected by the asteroid during that time, so Parasaurolophus Titanii was the last species of Parasaurolophus and one of the last native North American Hadrosaur, along with Kritosaurus Willardii. It lived from the Late Cretaceous around 73.2 million years ago to the Eocene period around 36 million years ago, when it finally became extinct for some unknown reason, probably due to competition from newer mammal herbivores related to, but not the ancestors to, today's mammals such as Brontotheres or maybe it was killed off by new mammal predators such as Hyaenodonts, or a bit of both, something that any species of Parasaurolophus could not adapt to, unlike Charonosaurus, which had adapted to competition and predation from mammal predators.
