酷東西

趣味知識

The name Ignavusaurus comes from the Latin word for 'coward' because it was found at a place called Ha Ralekoala, which means 'the place of the father of the coward'.1

The only known fossil of Ignavusaurus is a nearly complete skeleton of a baby that was less than one year old when it died.1

Its skull was broken into more than 120 pieces, but scientists were able to put it back together.1

Ignavusaurus had a long, slender neck and a long tail, just like its relatives Massospondylus and Melanorosaurus.1

Some scientists think Ignavusaurus might actually be a baby Massospondylus, because the two look very similar.1
