Description
This creature lived during Late Cretaceous where one day Eastern Asia would be.
The Ardeamimus sinensis (“egret mimic from China”) is a small deinocheirid that reached up to 2m tall when adult. These creatures were omnivores that inhabited mangroves, estuaries and coastal lagoons feeding on aquatic plants, algae and small animals.
These long snouted creatures were solitary most of the time, only congregating during nesting season when males gathered small harems in sandy coasts. The main form of display among these theropods was the complex and colorful structures on their heads and necks, a collective of pouches, wattles, flaps and other structures to impress females and intimidate other males.
Ardeamimus were also good runners and even considerable swimmers, making them able to adapt to the coastal environments and thrive to the point of becoming one of the biggest resident terrestrial creatures from the mangroves and estuaries.
