What is nomen dubium?

The phrase nomen dubium is a Latin term which literally means "dubious name".

Typically, a dinosaur is a nomen dubium if its holotype is deemed unfit for purpose, meaning the specimen to which its name was attached (aka "the name-bearing specimen") is in no fit state to be attaching a name to.

If a dinosaur's holotype is fragmentary, lacks important diagnostic features, lacks features that distinguish it from other species, or has been destroyed or lost, it may be replaced with a better specimen (a neotype)... if one is available.
