Episode 509: New Sauropods and the Yale Peabody has Reopened! Susan Butts joins us to clarify all of the modifications and upgrades on the newly renovated Yale Peabody Museum! Plus, new sauropods from Argentina embody Campananeyen and a few unnamed titanosauriforms. And Australotitan could also be 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.okay.a.) “Cooper” could also be 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 a protracted neck, a protracted tail, and walked on all fours
- Had a small head
- Most likely had a large physique
- Estimated by Gregory Paul to be about 98 ft (30 m) lengthy and weigh 55 tons (over 50 metric tonnes)
- One other estimate was it was 115 ft (35 m lengthy), based mostly on the femur (thigh bone)
- A 2020 estimate was over 81 ft (nearly 25 m) lengthy and weighing 37.5 tons (34 metric tonnes)
- One paper in 2017 confirmed skeletal and life restorations, with hypothesized osteoderms (spikes) on the tip of the again and starting of the tail, and appears like a really broad dinosaur
- Kind species is Ruyangosaurus giganteus
- Described in 2009 by Junchang Lü and others
- Genus title means “Ruyang County lizard”
- Genus title refers to Ruyang County of Henan Province
- Species title means massive in Greek, and refers to it being “an enormous sauropod dinosaur”
- In line with the paper that named the dinosaur: “The brand new sauropod clearly represents a brand new and gigantic dinosaur […] and represents the biggest dinosaur discovered from Asia thus far”
- One of many largest dinosaurs of the jap hemisphere
- Holotype features a couple vertebrae, a pair ribs, a part of the correct thigh bone, and a whole proper decrease leg bone (tibia)
- Two skeletons recognized
- Contains neck bones, again bones, a part of the hips, tail bones, ribs, a whole proper humerus (arm bone), a whole proper femur (thigh bone), and a whole proper tibia (decrease leg bone)
- There’s a big sauropod, Huanghetitan that was discovered close by, however the again vertebrae look totally different (Ruyangosaurus is way bigger)
- Extra strong than Huanghetitan
- Arduous to match with Huanghetitan, as a result of totally different bones have been discovered of every (can’t examine apples to apples), however the centrum of the again vertebra (center half) is way bigger, so would imply Ruyangosaurus was bigger
- Had a protracted, slender femur and quick, strong 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 50 in or 127 cm lengthy, and particulars within the arches
- Helps present there have been was extra range in sauropods within the Early Cretaceous in what’s now Asia, and presumably that point interval was key for the evolution and variety of huge titanosauriforms
- Different dinosaurs that lived across the similar time and place embody the sauropods Xianshanosaurus, Huanghetitan, and Yunmenglong, the ankylosaur Zhongyuansaurus, the oviraptorid Luoyanggia, in addition to ornithomimids, iguanodonts, and carcharodontosaurids
- On the time, international temperatures had been typically heat, and there have been in all probability seasons, which can have helped angiosperms unfold out, which can have helped titanosauriforms
Enjoyable Reality:
Big sauropods lived quite a bit longer than we thought.
