I Know Dino: The Big Dinosaur Podcast

Every megaraptoran dinosaur that has been described. Plus some that aren't officially named like the "Lightning Claw" from the opal fields of Australia. And many that have been given other classifications—like a potential giant compsognathid.

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
• Chilantaisaurus
• Datanglong
• Deltadromeus
• Eotyrannus
• Gualicho
• Siats
• Vectaerovenator
• Walgettosuchus
