Episode 509: New Sauropods and the Yale Peabody has Reopened! Susan Butts joins us to give an explanation for all of the adjustments and upgrades on the newly renovated Yale Peabody Museum! Plus, new sauropods from Argentina come with Campananeyen and a few unnamed titanosauriforms. And Australotitan is also a junior synonym.
Information:
- There’s a brand new rebbachisaurid, Campananeyen fragilissimus supply
- There are new titanosauriform sauropods within the Portezuelo Formation of Patagonia supply
- Australotitan (a.ok.a.) “Cooper” is also a junior synonym of the sauropod Diamantinasaurus supply
Interview:
Susan Butts, who’s the Director of Collections & Analysis on the Yale Peabody Museum, and her background is as an invertebrate paleontologist.

The dinosaur of the day: Ruyangosaurus
- Titanosauriform sauropod that lived within the Early Cretaceous in what’s now Henan, China (Haoling Formation)
- Very massive sauropod, so had an extended neck, an extended tail, and walked on all fours
- Had a small head
- Most certainly had a large frame
- Estimated by means of Gregory Paul to be about 98 feet (30 m) lengthy and weigh 55 heaps (over 50 metric tonnes)
- Some other estimate was once it was once 115 feet (35 m lengthy), according to the femur (thigh bone)
- A 2020 estimate was once over 81 feet (nearly 25 m) lengthy and weighing 37.5 heaps (34 metric tonnes)
- One paper in 2017 confirmed skeletal and existence restorations, with hypothesized osteoderms (spikes) at the finish of the again and starting of the tail, and looks as if an excessively large dinosaur
- Sort species is Ruyangosaurus giganteus
- Described in 2009 by means of Junchang Lü and others
- Genus title method “Ruyang County lizard”
- Genus title refers to Ruyang County of Henan Province
- Species title method massive in Greek, and refers to it being “an enormous sauropod dinosaur”
- In step with the paper that named the dinosaur: “The brand new sauropod clearly represents a brand new and gigantic dinosaur […] and represents the most important dinosaur discovered from Asia to this point”
- Probably the most greatest dinosaurs of the jap hemisphere
- Holotype features a couple vertebrae, a pair ribs, a part of the correct thigh bone, and an entire proper decrease leg bone (tibia)
- Two skeletons identified
- Contains neck bones, again bones, a part of the hips, tail bones, ribs, an entire proper humerus (arm bone), an entire proper femur (thigh bone), and an entire proper tibia (decrease leg bone)
- There’s a big sauropod, Huanghetitan that was once discovered within sight, however the again vertebrae glance other (Ruyangosaurus is far greater)
- Extra powerful than Huanghetitan
- Exhausting to check with Huanghetitan, as a result of other bones had been discovered of every (can’t evaluate apples to apples), however the centrum of the again vertebra (heart section) is far greater, so would imply Ruyangosaurus was once greater
- Had an extended, slim femur and brief, powerful tibia
- Is similar to Argentinosaurus (width of the again vertebra)
- Had shorter neural spines than Argentinosaurus
- Had a decrease neural backbone, a strong tibia that was once 50 in or 127 cm lengthy, and main points within the arches
- Is helping display there have been was once extra range in sauropods within the Early Cretaceous in what’s now Asia, and in all probability that time frame was once key for the evolution and variety of enormous titanosauriforms
- Different dinosaurs that lived round the similar time and position come with the sauropods Xianshanosaurus, Huanghetitan, and Yunmenglong, the ankylosaur Zhongyuansaurus, the oviraptorid Luoyanggia, in addition to ornithomimids, iguanodonts, and carcharodontosaurids
- On the time, world temperatures have been usually heat, and there have been most likely seasons, which could have helped angiosperms unfold out, which could have helped titanosauriforms
A laugh Reality:
Massive sauropods lived so much longer than we idea.
