Romeo: I was thinking about adding an FAQ to this post:1) If the dinosaur was radioactive, was it stronger than Godzilla?and so on .”The name comes from the fact that ornithischians have the pubis (one of the three hip bones per side) pointing backwards” Yes,exactly. I was trying to avoid being too technical especially without a handy drawing.

Insert “dinosaur” behind “most” in my second sentence.

It’s almost certainly a new species. Most species are known from parts of a single individual, and new ones are discovered once every three weeks or so.When uranium, thorium or the like occur in the groundwater, they often get stuck in fossil bones.

meaning, a dinosaur with a bird-like morphology.

Not at all, no. The name comes from the fact that ornithischians have the pubis (one of the three hip bones per side) pointing backwards, parallel to the ischium, rather than forwards, at 90° to the ischium. Birds share this condition, and so do segnosaurs and dromaeosaurids… all of these, birds included, are saurischians.

Radioactive dinosaur bones? It sounds like the beginning of a Japanese monster movie.
