The cover art here is actually by Richard A. Kirk, who I've worked with on several of my short-fiction collections. I asked if he'd like to do it, he said yes, and there you go. The ornithopod dinosaur being harassed by the velociraptorines is Lophorhothon atopus Langston, 1960. Originally described in the 1960s as a hadrosaur, Lophorhothon was briefly (and, as it turns out, incorrectly) suspected of being an "igaunodontian." Now, it's recognized a very basal hadrosaur. Anyway, the illustration is based on the mistaken belief that it was an igaunodontian, not a hadrosaur. It would look a bit different, correctly reconstructed.
By the way, the very first dinosaur I ever excavated was a specimen of Lophorhothon, way back in 1980.
Here's the cover:
