Avian Wing Proportions and Flight Styles: First Step towards Predicting the Flight Modes of Mesozoic Birds [PDF]

, 2011
We investigated the relationship between wing element proportions and flight mode in a dataset of living avian species to provide a framework for making basic estimates of the range of flight styles evolved by Mesozoic birds.

FIRST RECORD OF TRIASSIC DINOSAUR FOOTPRINTS FROM THE LOWER SANDSTONE UNIT OF KERSA AREA, EASTERN ETHIOPIA

Rivista Italiana di Paleontologia e Stratigrafia, 2020
Dinosaur footprints are described from the Lower Sandstone Unit of Kersa area, eastern Ethiopia. These are thought to belong to an early branch of theropods, and reported for the first time from Ethiopia. The evidence supports a Late Triassic age for the

The evolution and diversification of growth strategies in abelisauroid theropods

Theropods comprise a successful group of mostly predatory dinosaurs with varied growth rates that colonized all continents. Much research has addressed the histology of the Global North’s Mesozoic populations, especially coelurosaurians and allosauroids.
