    Dinosaur of the day Aniksosaurus and Aoniraptor, two predators on the smaller side for the Cretaceous. Aniksosaurus was probably under 10ft (3m) long and under 100lb (45Kg). Aoniraptor was twice as long and heavier, but it had a lot of air spaces in its bones to make it as light as possible..

    Megaraptorids could be closely related to Tyrannosaurs, but they had lighter skeletons and large impressive hand claws.

    The Meagaraptorans discussed in this episode:

    • Megaraptor: The original megaraptorid
    • "Lightning Claw" from the opal fields in Australia
    • Fukuiraptor: A slender megaraptorid with flat hand claws
    • Phuwiangvenator: One of the oldest genera (Early Cretaceous)
    • Vayuraptor: Another old genus from Thailand
    • Rapator: Opalized left hand bone found in 1905
    • Aerosteon: The aptly named "air bone" from Argentina
    • Australovenator: Also known as "Banjo" the largest predatory dinosaur in Australia
    • Joaquinraptor: One of the last surviving megaraptorans (Latest Cretaceous)
    • Maip: Largest known megaraptorid (30ft/9m and under 1.5 tons)
    • Murusraptor: Proportionally long snout from Argentina
    • Orkoraptor: The "toothed river thief" with specialized teeth and other features similar to compsognathids despite its large size
    • Tratayenia: Known from a handful of thin and hollow bones
    • Possible megaraptorans:
    • Bahariasaurus

    Dr. Steve Brusatte joins us for a paleontologist interview about The Story of Birds, exploring how birds survived the dinosaur extinction, evolved from dinosaur ancestors, and became one of Earth's most successful groups of animals.

    In this episode of I Know Dino, we cover new dinosaur discoveries and dinosaur research before sitting down with Steve Brusatte, paleontologist, author, and University of Edinburgh professor. We discuss what the fossil record reveals about bird evolution, why birds are living dinosaurs, and how paleontologists connect modern species to their dinosaur ancestors. Steve explains how scientists study dinosaur evolution, brain evolution, and the survival of bird lineages through the end-Cretaceous extinction.

    We also talk about giant fossil birds, terror birds, penguins that once rivaled large mammals, and how dinosaur research continues to reshape our understanding of prehistoric life. Along the way, Steve shares stories from his work as a researcher, science communicator, and author, including insights from writing The Story of Birds and helping connect modern bird biology to deep dinosaur history.

    Before the interview, we cover a new tiny alvarezsauroid from Argentina, discuss what it reveals about dinosaur evolution, and look at new research tools that help scientists reconstruct ancient environments and extinction events.

    Thanks for listening to I Know Dino: The Big Dinosaur Podcast—your source for dinosaur discoveries, dinosaur news, dinosaur research, paleontology news, and interviews with the scientists making new fossil discoveries.


    Steve Brusatte joins to discuss the only group of dinosaurs that survived the asteroid. Plus a new alvarezsauroid which is the most complete and smallest dinosaur ever found in South America.

    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 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

    Zofia Kielan-Jaworowska was a Polish scientist and the first woman to lead a dinosaur excavation expedition. On her explorations of the Gobi Desert, she discovered many famous animals, including Deinocheirus—a dinosaur that, for decades, was known only by its enormous, terrifying arms & claws. But when we finally found the rest of its body, it turned out to look more like Jar Jar Binks. This is the story of Zofia, and the dinosaur that surprised us all - as told originally aired on the History Dispatches podcast with Matt and McKinley Breen.
