This cast of a fossil of Nemicolopterus crypticus
This cast of a fossil of Nemicolopterus crypticus, one of the smallest pterosaurs, was discovered in northeastern China in 2008. Its fossil skeleton, with its curved toe bones, suggests it could cling to the branches or trunks of trees. Nemicolopterus, about the size of a modern sparrow, may have darted through forests hunting for insects, snapping them up in its toothless jaws.

Thalassodromeus sethi
Thalassodromeus sethi had a crest three times larger than the entire rest of its skull, when seen from the side. It had the largest crest of any known vertebrate. This large pterosaur species, with a wingspan of 14 feet, lived around 110 million years ago near a lagoon in what is now Brazil. #pteorsaurs
