Episode 420: PalaeoPoems with Brigid & Mike. Plus ‘Spinosaurus shouldn’t be an aquatic dinosaur’ in keeping with a brand new paper, a brand new T. rex happening show, Large Al pathologies, and our SVP wrap up
Information:
- “Spinosaurus shouldn’t be an aquatic dinosaur” in keeping with a brand new evaluation of its buoyancy and physique form supply
- A T. rex skeleton, nicknamed Shen, was presupposed to go on sale however as a substitute might be on show at a museum (for now) supply
- The Pure Historical past Museum in London is getting a Patagotitan supply
- Our final protection of SVP 2022 together with pachycephalosaurs, Large Al pathologies, hen hearts, and extra supply

The dinosaur of the day: Eucamerotus
- Sauropod that lived within the Early Cretaceous in what’s now the Isle of Wight, England (Wessex Formation)
- Seemed like different sauropods, with a protracted neck, 4 columnar legs, and small head
- Depicted as neck extra upright, like Brachiosaurus
- One estimate to be about 49.2 ft or 15 m lengthy, primarily based on the vertebrae, and assuming it’s a brachiosaurid
- Sort species is Eucamerotus foxi
- Genus title means “well-chambered”
- Refers back to the hollows of the vertebrae
- Named by William Blows in 1995
- John Hulke named Eucamerotus in 1870, however didn’t give it a species title
- Hulke wrote in 1870 about “the neural arch of an enormous Wealden vertebra”
- Described a neural arch that William Fox discovered
- Later Hulke referred Eucamerotus to be a junior synonym of Ornithopsis
- Ornithopsis was a medium-sized sauropod (genus title means “bird-likeness”)
- In 1882 Hulke described pelvis fossils as Ornithopsis eucamerotus
- Hulke wrote in 1882 concerning the pubis and ischium of Ornithopsis eucamerotus that the late Rev. W. Fox, who discovered the bones: “permitted me to take a tough sketch of them, however for a very long time he wouldn’t enable their full extrication from the rock, nor the readjustment of the numerous fragments into which they had been damaged” (ultimately the British Museum reconstructed the fossils)
- William Blows in 1995 mentioned Eucamerotus was a sound brachiosaurid
- Species title after William Fox who collected a lot of the fossils (later assigned by Blows because the paratypes)
- Blows mentioned that Owen, Seeley, Hulke, and others established a number of sauropods “principally primarily based on insufficient materials”
- Ornithopsis hulkei was named primarily based on two dorsal centra
- Blows discovered that solely the holotype of Ornithopsis was Ornithopsis and that different fossils referred to Ornithopsis had been both Eucamerotus or Sauropoda Incertae Sedis
- Ornithopsis and Eucamerotus have additionally up to now been synonymized with Pelorosaurus, however Blows mentioned they need to be thought-about separate as a result of not one of the kind specimens have overlapping fossils to check with
- Blows referred dorsal vertebrae and different fossils (5 paratypes) to Eucamerotus, however not everybody agrees with this, as a result of they don’t have the identical options because the holotype (the strong parapophyses)
- SV-POW wrote about how each Ornithopsis and Eucamerotus had been named primarily based on kind specimens that had been “fairly undiagnostic”, although the neural arch of Eucamerotus does have one distinctive function (strong parapophyses, projections of vertebrae)
- In 2001 Naish and Martill recommended Eucamerotus was a doubtful brachiosaurid, and Upchurch and others in 2004 thought-about it to be doubtful
- Campbell and others in 2017 discovered Eucamerotus to be legitimate (although unsure if it was peer reviewed?)
- There’s one other specimen, generally known as the Barnes Excessive Sauropod, which may be Eucamerotus
- Undescribed, however present in 1992 within the Wessex Formation and is about 40% full, with similarities within the vertebrae to Eucamerotus
- Nevertheless, the possession of the specimen is difficult and doesn’t sound prefer it’s obtainable to researchers
- Lived in a semi arid atmosphere with a lot of conifers and ferns
- Different dinosaurs that lived across the similar time and place included sauropods, theropods reminiscent of compsognathids, spinosaurs, tyrannosaurs, raptors, ornithischians reminiscent of iguanodonts and heterodonts
- Different animals that lived across the similar time and place included fish, turtles, plesiosaurs, pterosaurs, and mammals
Enjoyable Truth:
Ceratopsians broke and misplaced their horns in many alternative methods.
