'Monkeydactyl' may be the oldest known creature with opposable thumbs
The winged reptiles dexterity may have helped it climb trees during the age of dinosaurs
A newly discovered pterosaur (illustrated) from the Jurassic Period may have used its opposable thumbs to cling to tree branches and catch food such as cicadas.

Future Jurassic Park films could feature one weird new beast in the menagerie: a pterosaur nicknamed Monkeydactyl for its opposable thumbs.
This flying reptile from the Jurassic Period may be the earliest known animal that could touch the insides of its thumbs to the insides of its other fingers, researchers report online April 12 in Current Biology. Such dexterity probably allowed Monkeydactyl to climb trees about 160 million years ago, perhaps to feed on insects and other prey that nonclimbing pterosaurs did not, the researchers say (SN: 12/21/18). The latter half of the creatures official name, Kunpengopterus antipollicatus, comes from the words opposite and thumb in ancient Greek.
Monkeydactyls fossilized remains, unearthed in northeastern China in 2019, are embedded in rock. So the team used micro-CT scanning to create a 3-D rendering of the fossil. With this detail, were able to look at the fossil from any angle, and make sure that the bones are in their right [original] place, says study coauthor Rodrigo Pêgas, a paleontologist at the Federal University of ABC in São Bernardo do Campo, Brazil.
