Episode 369 is all about Saturnalia, a small Late Triassic sauropodomorph that will have hunted small prey.
We additionally interview Richard Fallon, a Leverhulme Belief Early Profession Fellow on the College of Birmingham, who research the interactions and overlaps between literature and science. He’s additionally the writer of the e-book, Reimagining Dinosaurs in Late Victorian and Edwardian Literature. Observe him on Twitter @dr_r_fallon.

On this episode, we focus on:
Information:
- A T. rex skeleton which was not too long ago mounted in Higher Bavaria, Germany might be returning to the US supply
- London’s Pure Historical past Museum dressed up their animatronic T. rex in a “Jurassic jumper” supply
- Jurassic World: The Exhibition goes to Denver, Colorado on March 4, 2022 supply
The dinosaur of the day: Saturnalia
- Basal sauropodomorph that lived within the Late Triassic in what’s now Brazil (Santa Maria Formation of Rio Grande) and probably Zimbabwe (Pebbly Arkose Formation)
- Had a mixture of sauropodomorph and theropod traits (exhausting to categorise)
- Small, with an extended neck and lengthy tail, and brief arms
- Gracile physique
- Estimated to be 5 ft (1.5 m) lengthy
- Sort species is Saturnalia tupiniquim
- Named in 1999 by Max Langer and others
- Genus title means “carnival” in Latin and refers back to the fossils being discovered through the feasting interval
- Species title comes from Portuguese and Guarani and is “an endearing manner of referring to native issues from Brazil”
- Saturnalia was a preferred Roman competition, devoted to the Roman god Saturn
- Initially celebrated on December 17, then prolonged to final a full week
- Celebrated with a sacrifice on the Temple of Saturn, banquet, reward giving, and plenty of events/carnivals (additionally allowed to gamble)
- Additionally named a mock king (Saturnalicius princeps)
- Presents included wax collectible figurines, cube, combs, toothpicks, axes, perfumes, parrots, clothes, books, and extra
- Typically had verses to go together with the items (like playing cards as we speak)
- Lots of the Saturnalia customs turned customs or influenced Christmas and New 12 months
- Saturnalia named based mostly on three partial skeletons, all present in the identical space in 1988
- Holotype features a well-preserved, semi-articulated skeleton (vertebrae, pectoral girdle, proper humerus, partial proper ulna, pelvic girdle, left femur, many of the proper hind limb)
- Paratypes embody partial mandible with tooth and partial skeleton (vertebrae, pectoral girdle, proper humerus, proper aspect of the pelvic girdle, many of the proper hind limb)
- Attainable a partial femur present in Zimbabwe belongs to Saturnalia
- Second dinosaur discovered within the Carnian “Alemoa-beds” of southern Brazil, one of many oldest strata with dinosaur fossils
- Discovery helped present proof of widespread distribution of early sauropodomorphs within the Late Carnian
- In 2003, Max Langer revealed extra particulars concerning the anatomy
- Discovered the primary metatarsal to be a lot shorter than second and third ones (60% the size of the second, 55% the size of the third)
- Had scars and different traces of muscle attachments
- Discovered it had limbs tailored to operating, extra so than typical sauropodomorphs
- May stroll on two or 4 legs, however most likely bipedal when transferring quick
- In all probability not an compulsory biped
- In all probability walked on two legs extra usually than different prosauropods, to run away from predators or hunt for small prey
- Gait was “most likely someplace between that of a totally bipedal dinosaur like Coelophysis and that of types similar to Plateosaurus, which have been primarily quadrupedal, turning into bipedal solely at excessive speeds”
- In 2017, Mario Bronzati and others studied the endocast of Saturnalia
- Appeared on the floccular fossae lobe (FFL), which is “a part of the programs working to manage eyes, neck, and head actions”
- The obvious smaller quantity of FFL in sauropods has previously been considered linked to sauropods being quadrupedal (concept is you want extra steadiness management when bipedal versus quadrupedal, and steadiness includes the FFL and internal ear)
- However, FFL quantity has been discovered to fluctuate in different dinosaur endocast research, together with theropods, so FFL is probably not associated to locomotion
- Attainable {that a} well-developed flocculus might be linked to predatory habits, as a result of it helps the dinosaur transfer its neck and cranium rapidly
- Additionally studied the tooth and located recurved tooth with small serrations
- Based mostly on finding out Plateosaurus and Saturnalia, potential FFL went down in bipedal sauropodomorphs earlier than they advanced to be quadrupedal, and should have been linked to their herbivorous weight-reduction plan
- In 2019, Mario Bronzati and others studied the cranium stays of Saturnalia
- CT scanned the cranium bones of one of many paratypes
- Discovered that the small cranium could also be associated to “an elevated effectivity for predatory feeding habits, permitting quick actions of the top with the intention to safe small and elusive prey” (helps the endocast examine)
- Had a brief cranium
- Cranium light-weight and was about 3.9 in (10 mm) lengthy, small in comparison with the remainder of the physique
- To recap, small cranium helped with the lengthy neck, which helped later sauropods eat vegetation different animals couldn’t attain, and ultimately gave them a bonus and helped them develop so giant
- Could have been capable of transfer its head rapidly, and go after small prey
- Had heterodont tooth, the place some have been extra leaf-shaped and others larger and coarsely serrated
- Could have been omnivorous, consuming lizards, mammals, bugs, and should have additionally eaten vegetation
Enjoyable Truth: In 2017 a nest of about 20–30 fossilized dinosaur eggs was discovered on Christmas morning.
