Episode 468: What to feed a dinosaur. Ali Nabavizadeh, knowledgeable in dinosaur feeding biology, joins us to speak about which fashionable meals other dinosaurs may consume. Plus a brand new Triceratops frill that was once chewed on through a T. rex
Information:
- An undergraduate scholar discovered one of the most greatest theropod fossils within the japanese U.S. supply
- There’s a possible new certificates of paleontology for undergrads at Utah State College supply
- New proof of Tyrannosaurus biting Triceratops proper at the frill supply
- Hadrosaurs could have had muscle tissue for chewing (no longer simply biting and swallowing issues entire) supply
- Phrases topic, and medical names could have an affect on how one thing is perceived supply
- Researchers analyzed paleontology documentaries supply
- Why Dinosaurs? documentary had its Hollywood premiere supply

The dinosaur of the day: Liaoceratops
- Ceratopsian that lived within the Early Cretaceous in what’s now Liaoning Province, China (Yixian Formation)
- Small, walked on two legs
- Could have regarded moderately very similar to Psittacosaurus, however with a brief frill on its head
- Described as hare-sized
- Estimated to be about 1.6 feet (50 cm) lengthy and weighed 4.4 lb (2 kg)
- Estimated to be about 1 feet tall (0.3 m)
- Holotype cranium was once about 6 in (154 mm) lengthy
- Cranium identical in measurement to Psittacosaurus
- Simplest skulls discovered thus far
- No horns
- Had small neck frill
- Had a small horn that confronted sideways underneath each and every of its eyes, which was once small and light-weight, so could have been for show
- Had pitted floor texture at the edges of the frill that display there have been jaw muscle tissue that went at the back of the cheek and hooked up to the frill, which was once thick
- Ate vegetation, reminiscent of in all probability ginkgo, horsetails, or conifers, that have been discovered within sight
- Sliced and sheared its meals, as a substitute of grinding
- Most certainly concealed or ran away when it had to shield itself
- Early relative of ceratopsids
- A part of the department (Neoceratopsia) that ended in ceratopsians like Triceratops (any other other department contains Psittacosaurus)
- Is helping display the early evolution of ceratopsians and that the break up came about a minimum of through the Early Cretaceous, about 130 million years in the past
- Is helping display that the huge ceratopsians like Triceratops developed from small ancestors, and that ceratopsians were given a few of their distinct options early and extra temporarily then scientists prior to now idea
- Named in 2002 through Xu Xing and others
- Sort species is Liaoceratops yanzigouensis
- Genus title method “Liaoning horned face”
- Species title refers back to the the city Yanzigou
- Holotype features a just about entire subadult cranium
- Different skulls discovered, together with a juvenile cranium and a good more youthful partial cranium and jaw from a smaller person (no cranium roof, or braincase, or left cheek area, which may well be because of a, more than likely small, predator consuming its mind)
- Regarded as a small predator as a result of when small owls like screech owls move after prey, they “dismember the carcass small chew through small chew” in comparison to nice horned owls that swallow mice entire, consistent with You Hailu and others
- One of the most juvenile skulls is set part so long as the holotype
- A 2023 learn about of the interior of the cranium discovered that Liaoceratops had a slightly massive olfactory bulb, so more than likely had a just right sense of scent, and had different main points that recommend it had a strong gaze and saved its head just about horizontal
- Additionally discovered that it had slightly brief cochlear ducts, so more than likely may listen slightly top frequencies
- And located proof suggesting that grownup Liaoceratops was once agile on two legs and moved in a similar way to an grownup Psittacosaurus
- A learn about of the enamel of Liaoceratops in 2018 discovered that it changed enamel with step by step greater enamel because it grew to stay alongside of its rising jaws
- Additionally discovered proof of the beginnings of dental batteries, or a minimum of characteristics that ended in the evolution of dental batteries
- Lived in a rainy, humid local weather with dry seasons, and a median every year temperature of fifty levels F (10 levels C)
- Different animals that lived round the similar time and position come with bugs, and lots of dinosaurs reminiscent of Psittacosaurus, troodontids Mei (the dozing one), Sinovenator, and Daliansaurus, dromaeosaur Graciliraptor, the oviraptorosaur Incisivosaurus, the ornithomimosaur Shenzhousaurus, mammals, amphibians, fish
- Additionally discovered flowering vegetation
Amusing Reality:
Triceratops had muscle tissue operating partly up the entrance of its frill, very similar to our temporal muscle tissue.
