What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

Bats are the only flying mammals but their transition to flight remains poorly understood and controversial. We applied aerodynamic modeling to reconstruct flight in the oldest complete fossil bat, the archaic Onychonycteris finneyi from the early Eocene of North America, under paleo-atmospheric conditions. Results indicate that Onychonycteris was...

... The evolution of flight and the size of flying animals is also a useful proxy for paleo air density. Muscle power, takeoff airspeeds, thermoregulation and respiration can be modelled suggesting that the giant volant insects of the Permian required ∼2 bar to function (Cannell & Nel, 2023); the Miocene giant birds probably flew in air at 1.3 bar (Cannell, 2020) and bats evolved at 1.6 bar (Giannini et al., 2024). Again, the 'hexapod gap' , around 380-320 Mya, a period in which there is a paucity of winged insect fossils (Schachat et al., 2018), suggests a low-density atmosphere in which gliding and subsequent flapping flight could not efficiently develop . ...
