I Know Dino: The Big Dinosaur Podcast

A new troodontid with a skull like a pachycephalosaur, two new prehistoric birds, the bird evolutionary tree, how birds developed the ability to fly, how we know Microraptor turned out to be a decent flier, and a mathematical rule that shapes theropod faces

Dinosaur of the day Archaeopteryx , the "ancient wing" dinosaur that was originally named for just a single feather, but is now known from over a dozen individuals.
In dinosaur news this week:
A new troodontid theropod, Xenovenator espinosai, has an extremely thick skull—like a pachycephalosaur
Scientists have created a complete evolutionary tree of all birds (over 9,000 species)
There’s a new neoavian Aequornithes bird from Antarctica, Pujatopouli soberana
There is a new euornithean bird, Kunpengornis anhuimusei, that has gut contents!
How the structure of feathers in the Cretaceous tells us about their evolution
The specialization of a small wrist bone, the pisiform, helps birds to fly
A key wing muscle that helps birds fly appears to have evolved by fusing cells from multiple muscles
How often birds, bats, and insects flap when flying may be related to a built in constraint related to the vortex their wings generate with each flap
More Microraptor specimens (with soft tissues!) show it was a decent flier
A set of raptor dinosaur tracks indirectly shows it used its arms to help it run faster
Just because a theropod dinosaur had short arms and not many fingers, doesn’t mean their hands and arms were useless
Birds have a special organ to help them balance (which doesn't seem to matter as much for flight)
Birds have been nesting in the Arctic for at least 73 million years
How theropod dinosaur (non-avian and bird) faces are shaped may have followed a mathematical rule
A study of the Chicago Archaeopteryx found that could definitely fly
Birds need a lot of calories to fly, and Archaeopteryx, the oldest known bird, has three features modern birds also have to eat efficiently

A New Jurassic neornithischian dinosaur with a Voice Box. Pulaosaurus qinglong, from China’s Tiaojishan Formation, has only the second larynx ever found preserved with a non-avian dinosaur. Source
The small ornithischian Enigmacursor mollyborthwickae was found in the Morrison Formation of Colorado. Reminding us that it wasn't just huge sauropods and stegosaurs eating plants in the Late Jurassic. Source
A new ornithopod named Obelignathus septimanicus was identified from a stronger jawbone than other Late Cretaceous ornithopods (like Rhabdodon) in what is now southern France. It's name refers to the French comic character Obelix who has superhuman strength (like the "unusually robustly-built" jawbone on Obelignathus). Source
An Early Cretaceous basal hadrosauroid, Cariocecus bocagei, was named from Portugal. It had a fused upper jaw and cheekbone, possibly letting it chew tougher plants than its relatives. Source
