Episode 287 is all about Callovosaurus, a Dryosaurid which is featured in some editions of Jurassic Park (the first book).
We also interview Dr. Steve Poropat from Swinburne University & Research associate at Australian Age of Dinosaurs and Adele Pentland PhD candidate at Swinburne University & Research associate at Australian Age of Dinosaurs.
Here’s an artistic rendering of the new elaphrosaur in action. Can you spot Nessy in the image below? (Hint: It’s not in the water, zooming required)

The dinosaur of the day: Callovosaurus
- Iguanodontian that lived in the Middle Jurassic in what is now England (Oxford Clay Formation)
- Known from a nearly complete left thigh bone (0.92 ft or 28 cm long)
- Partial tibia (shin bone) found near by may be Callovosaurus
- Estimated to be 8.2 ft (2.5 m) long
- Type species is Callovosaurus leedsi
- Genus name means “Callovian lizard”
- Callovian is an age and stage in the Middle Jurassic, fossil found in middle Callovian
- Described in 1889 by Richard Lydekker, originally named Camptosaurus leedsi
- Species name in honor of the collector Alfred Nicholson Leeds
- In 1980, Peter Galton analyzed the fossil and named it as a new genus, Callovosaurus
- Some scientists thought it was a dubious iguanodontian
- Femur was found in a brick pit near Fletton
- Femur was originally complete, and now is in three pieces that fit together
- Cast of the femur made in 1888
- In 1909, Gilmore said that Camptosaurus leedsi was similar to Camptosaurus but “if referable at all to an American genus, its closest affinities, as indicated by the femur, are with Dryosaurus”
- In 2006, Jose Ignacio Ruiz-Omeñaca and others found it to be a valid genus, and the oldest known dryosaurid
- Originally classified as Camptosauridae, now Dryosauridae
- Femur is similar to Dryosaurus and Valdosaurus
- Closest relative is Dryosaurus
- Other animals that lived around the same time and place included ichthyosaurs, plesiosaurs, crocodyliforms, pterosaurs, the sauropod Cetiosaurus, the stegosaurs Loricatosaurus and Lexovisaurus and the ankylosaur Sarcolestes
- Replaces Microceratus in some editions of the first novel, Jurassic Park
- One of the dinosaur toys in Jurassic World Attack Pack
Fun Fact: Birds have skulls with many features of their baby Mesozoic dinosaur counterparts (bird skulls are paedomorphic).
