Episode 227 is all about Incisivosaurus, a small dinosaur with rodent-like entrance tooth.
We additionally interview Alida Bailleul, who just lately described a dinosaur fossil with an unlaid egg clearly in its stomach. Her analysis focuses on microscopic construction of dinosaur bone and tissue. She has additionally studied trendy alligators and birds to study dinosaur tissue and biomechanics.

Information:
- A brand new small therizinosaur, Lingyuanosaurus sihedangensis, was found with smaller extra curved claws than its relative Therizinosaurus supply
- “Scotty” the T. rex is now formally the biggest Tyrannosaur—and probably land predator—ever found supply
- A tremendous discover of a dinosaur, Avimaia schweitzerae, that died with an unlaid egg inside it was present in Northwest China supply
- Washington State is engaged on getting an official state dinosaur: Suciasaurus rex supply
- The Montana state senate handed the invoice 50-0 that claims fossils are a property’s floor rights, not mineral rights supply

The dinosaur of the day: Incisivosaurus
- Oviraptorosaurian theropod that lived within the Early Crecateous in what’s now China
- Most likely an herbivore or probably an omnivore
- Described in 2002 by Xu and others, based mostly on a cranium discovered within the Yixian Formation
- Title means “incisor lizard”
- Cranium is about 3.9 in (10 cm) lengthy
- Had an extended snout that was about half the size of the cranium, and a slender decrease jaw
- Had rodent-like entrance tooth (massive and flat), that was worn down in an identical strategy to herbivorous dinosaur tooth
- Had small, peg-like tooth within the again
- Had plenty of tooth, and cranium had some options that confirmed a relationship with therizinosaurs (different theropods that have been in all probability herbivores)
- Balanoff and others scanned the cranium in 2009
- Had primitive traits (just like the tooth) that will present the similarities between oviraptorids and birds are due to convergent evolution, and weren’t shared derived characters
- Estimated to be about 3.3 ft (1 m) lengthy
- Might have been feathered (based mostly on family)
- Kind species is Incisivosaurus gauthieri
- Species title is in honor of Dr. Jacques Gauthier, recognized for classifying phylogeny
- Hypothesis that it’s synonymous with Protarchaeopteryx, however want extra fossils to know for positive
Enjoyable Truth: Cassowaries seem to make use of their casques for thermoregulation. Some non-avian dinosaurs could have additionally used their head crests for thermoregulation.
