New Bird-Like Dinosaur from Mongolia Had Extremely Robust Hands
Paleontologists have identified a new species of dromaeosaurid dinosaur from an almost complete and articulated skeleton found in the 2000s in Mongolia.Life reconstruction of Shri predict.

Based on several derived features in its skull, vertebrae and skeleton, the species is referrable to a group of bird-like theropod dinosaurs called the Dromaeosauridae.
Named Shri predictit is only the second species in its genus; the other species, Shri deviwas described in 2021.
“Dromaeosauridae is a clade of small- to medium-sized theropod dinosaurs known from several Cretaceous units from North America, Asia, Europe, South America and eventually Antarctica and Madagascar,” said lead author Andrea Cau and colleagues.
“Feather-like integumentary structures, true pennaceous feathers and...
Microraptorine Dinosaur Footprints Shed New Light on Origin of Flight
Top Stories Tamfitronics Theropod dinosaur trackways can be used as indirect evidence of pre-avian aerial behavior, according to new research.The animal responsible for Dromaeosauriformes are rare tracks is believed to be a small microraptorine dinosaur related to the ancestors of birds. Image credit: Julius Csotonyi.In the study, University of Maryland paleontologist Thomas Holtz Jr. and his colleagues examined two-toed footprints produced by a small, bird-like microraptorine dinosaur moving at high speed.Scientifically named Dromaeosauriformes are rarethese footprints are nearly 100 million years old (Cretaceous period) and were found preserved in a slab of rock in South Korea.“This guy is dinky — one of the smallest dinosaurs that we have fossils of,” Dr. Holtz said.“These tracks were a puzzle because their footprints are so tiny but they’re so far apart.”The paleontologists found that the producer of Dromaeosauriformes...
