Dinosaur of the day Beishanlong, the "North Mountains dragon" from Gansu China.

Interview with Jessie Atterholt, assistant professor at the Western University of Health Sciences. She's also the lead author of the new paper "The most complete enantiornithine from North America and a phylogenetic analysis of the Avisauridae." You can follow her on Instagram @theladyanatomica or jessieatterholt.com

In dinosaur news this week:

  • The smallest dinosaur footprints ever were discovered found in South Korea
  • Differences in Dilong and T. rex braincases show how tyrannosaurs changed as they evolved
  • The most complete North American enantiornithine, Mirarce, was found

Dinosaur of the day Montanoceratops, a primitive ceratopsian with an unusually deep tail thanks to its vertebral spines.

Interview with Ashley & Lee Hall, both from the Cleveland Museum of Natural History. Ashley is the Adult Programs Coordinator and Lee is a Preparator and Lab Manager. But more importantly, like us, their wedding heavily featured dinosaurs.

In dinosaur news this week:

  • T. rex could turn more quickly than similar dinosaurs
  • New histology on the tyrannosaurs Jane & Petey show that Nanotyrannus is probably a juvenile T. rex
  • Simulated jaw mechanics showed the bite force and bone penetration of several tyrannosaurs
  • The juvenile T. rex Found N.E. Montana includes partial hands, feet, vertebrae, ribs, a partial skull, and teeth
  • Therizinosaurs have an unusual combination of basal arm musculature and more avian style leg musculature
  • Dinosaurs’ unique single ovary appears to have evolved after Oviraptor but before Troodontidae
  • We don't know if large bodied dromaeosaurs (velociraptor and larger) had tail fans
  • The new "Mtuka titanosaur" was found in Africa
  • An analysis of fossil fragments in Mygatt-Moore showed about half of the bones had marks on them
  • Maiasaura humeri bone microstructure changed as they aged, supporting a shift from bipedal to quadrupedal
  • Pachycephalosaurus has theropod-like teeth in the front and other similarities to Dracorex
  • An analysis of the pachycephalosaur Sphaerotholus showed that all 3 species should be considered valid
  • Early dinosaurs had thin semi rigid eggs, but in the early to mid Jurassic their eggs got thicker—possibly as a solution to dehydration and predation
  • By studying dozens of crocodilian, turtle, and bird nests, researchers found that the arrangement is preserved well as it is buried
  • Professional fossil preparator tips include: wear gloves, use tools only after getting training, and test other methods in advance to avoid unwanted destruction
  • High quality photogrammetry and 3D printing can be achieved using cheaper equipment
  • It is important to standardize and clean up the large amounts of historical fossil data so that it is easy to search and understand

Nov 7, 2018

Dinosaur of the day Zuniceratops, a ceratopsian that was discovered in New Mexico by an 8 year-old.

Interview with Jingmai O'Connor, professor at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences who recently described the first ever fossilized dinosaur lung remains.

In dinosaur news this week:

  • A 130 million year old fossil from Hebei Province in China has been found
  • The “Baofenglong fossil” recently went on display at Chongqing Yongchuan Museum Town Hall in China. An 80% complete 49 ft (15 m) long herbivore
  • Residents near the Tumbler Ridge Museum voted to fund the museum with added attractions and services
  • Most sauropod fossils are from adults. Dwarf sauropods have a younger distribution, but still mostly adults
  • Several models of Yi qi extra wrist bone were proposed to find an orientation that may have worked with its patagial membranes
  • Flight evolution can be categorized into 4 evolutionary phases: characters unrelated to flight, exapted traits, direct selection, and traits for longer flight duration
  • Pterosaurs and maniraptorans couldn’t assume a bat-like pose
  • Microraptor & Rahonavis could glide, Changyuraptor used it's tail for pitch control, but troodontids were too big (relative to their wings) to get off the ground
  • Ichthyornis has a skull half way between Archaeopteryx and modern birds
  • "Birds are the only group of animals that rival mammals in terms of brain size"
  • Sauropod trackway “gauge” might not mean much
  • A synchrotron of coprolite from an early dinosaur like Silesaurus opelensis showed lots of beetle remains including wings & beetle tibia
  • Based on carbon-13 isotopes in Deinonychus and Tenontosaurus it appears that raptors were not pack hunters
  • Thanks to guinea fowl walking through soft mud we are closer than ever to recreate how dinosaurs made their tracks
  • The pectoralis of Archaeopteryx was smaller than modern birds, but may have still been large enough to achieve brief flight
  • A study of Psittacosaurus braincases shows that 2 year-old brains elongate significantly (midbrain & olfactory tract/bulbs especially)
  • Ugrunaaluk was smaller than its massive cousins like Edmontosaurus, possibly because of dwarfism from living in the arctic reaching about 18-19ft long
  • A new ceratopsian was found in Grand staircase Escalante National Monument
