2022 $1 Australian Dinosaurs - Elaphrosaurine theropod Coin & Stamp Cover PNCThe elaphrosaurine theropod has not yet been assigned to any genus, as its skeleton is so incomplete. It was a toothless theropod ("three-toed") dinosaur species related to Elaphrosaurus (light-footed lizard).This dinosaur has been described from a single neck vertebra bone discovered near Cape Otway in Victoria in 2015. The sediments at the site date from the Early Cretaceaous around 110-107 million years ago.During this period, the climate of the Cape Otway region was cold, indicating that this animal could tolerate near-polar temperatures, which were warmer than that area today, as there were no ice caps.It ran low to the ground on two legs, and had a slender body, long neck, stubby arms and possibly toothless skull.It probably had a plant-based diet and did not hunt prey. Evidence suggest that elaphrosaurs started life eating a range of foods, possibly including tiny monotremes, insects and fruits, but shed their teeth as they aged, to be replaced by a horney beak.The coin's obverse features the Jody Clark effigy of Her Majesty Queen Elizabeth II and the monetary denomination.Affixed to the envelope is an official Australia Post International $1.10 stamp.
