Steropodon was a small mammal that lived alongside the dinosaurs in the mid-Cretaceous time period.
Facts[edit | edit source]
Steropodon was a prehistoric species of monotreme, or egg-laying mammal, that lived during the middle Albian stage, in the Lower Cretaceous period. It was once thought to look like a platypus though this is now known to be incorrect.
In Walking with... Series[edit | edit source]
In the fifth episode of Walking with Dinosaurs, a Steropodon (live acted by a coatimundi) is seen attempting to steal eggs from a Leaellynasaura; however the dinosaur drives it off by kicking dirt back at it.
Errors[edit | edit source]
- Steropodon was a monotreme; at the time the WWD series, it was thought to be similar to the modern platypus. Yet it was depicted by a live Coatimundi, which looks nothing like a platypus, and presumably not at all like what one would expect Steropodon to look like. However, recent studies on a relative, Teinolophos, show that it was a rather different animal from modern platypuses, lacking a beak and having teeth, so in retrospect WWD's depiction was justifiable (though one shouldn't expect Steropodon to look exactly like a Coatimundi either).
