Episode 259 is all about Chingkankousaurus, a possible tyrannosauroid from eastern China known only from a shoulder blade.
We also interview Phoebe Wood, a primary student from Adelaide, South Australia. She won several awards for her Anchiornis huxleyi model. Including Young Scientist of the Year 2019 and the Oliphant Trophy—a first for a primary school student.

In this episode, we discuss:
- News from the final day of talks and posters at the 2019 meeting of the Society of Vertebrate Paleontology source
- A large varied selection of dinosaur microfossils from the Alaskan Kakanaut Formation show that dinosaurs lived in the arctic year-round
- After more restoration work, an alternative Allosaurus holotype is ready to be named
- Siats and Moros finds show that Allosauroids and Tyrannosauroids coexisted in the cretaceous
- We now have an excellent growth series of over 20 Sinornithomimus individuals from China
- A coprolite “nugget” shows excellent preservation of at least two feather types and likely multiple ticks
- More evidence shows that dinosaur diversity was very high up until the end-cretaceous extinction
- By comparing LAGs in arm and leg bones, another study shows that Maiasaura was quadrupedal its whole life
- A new Jurassic ankylosaur was found in Portugal
- Two new ceratopsians were discovered in Grand Staircase Escalante National Monument
- A new “Super matrix” of crocodilians places some difficult taxa in a cladogram
- An analysis of Dimetrodon (not a dinosaur) and its relatives shows the wide range of sizes that they came in
- The Tate Geological Museum have found a couple of sauropod feet and a diplodocid skull
- The Burke Museum in Washington has a new exhibit called Fossils Uncovered source
- A new animation shows how long dinosaurs lived, by tracing our solar system’s movement through the Milky Way Galaxy source
- Horse Archer Productions has a new web series, A Million Bones of Stone, the first episode is about Laelaps source
- Justice Smith and Daniella Pineda, who played Franklin and Zia, in Fallen Kingdom will be back for Jurassic World 3 source
The dinosaur of the day: Chingkankousaurus
- Theropod that lived in the Late Cretaceous in what is now Shandong province in eastern China (Wangshi Group)
- Only one species: Chingkankousaurus fragilis
- Named for the village Chingkankou (Jingankou), near where it was found
- Described by Yang Zhongjian (a.k.a. C.C. Young) in 1958 from one scapula, which he said was basically like Allosaurus but smaller
- Some scientists thought the shoulder bone was a rib or part of gastralia, but a 2013 study found that to be unlikely
- Dan Chure assigned the fossil to Coelurosauria in 2001, and a few years later scientists refined that to a tyrannosauroid
Fun Fact: There have been two Anchiornis specimens studied for their coloration patterns: one with orange head feathers and one without.
