This paleontological restoration is inaccurate, or its accuracy is disputed.
Reason: The pterosaurs depicted are highly outdated, lacking pycnofibers and airsacs on their bodies, having pointed wingtips, etc. The pterosaurs depicted are most likely
Pteranodon
, but these types of pterosaurs are long extinct before the K-Pg extinction occurred.

Chicxulub impact site December 28, 1994 This painting by Donald E. Davis depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures which persisted for at least a decade. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. |
