Really, a 20 mile wide crater/eco system with 20 ton land carnivores and sea creatures weighing many times more? How would that ever be supported and how long would the food supply last?. Almost everything in this book is carnivorous and nothing makes any sense going from there - where's the prey (except for some small armadillo type critters) . The first book was better written and much better thought out.Actually the research in the second book is terrible.According to the story this was a 20 mile wide crater so we have :20 miles  2 = radiusradius = 10 milesArea equals Pi times r times rArea = 3.14  (10 miles)  (10 miles)Area = 314 sq. milesSo, in a 314 sq mile crater you have multiple 20 ton land carnivores and multiple 100 ton water carnivores, plus other large spider like and scorpion like carnivores.What did they eat in that tiny land area? A 7 ton T Rex probably ate over 500 lbs at one meal but was not able to find a meal like that every day. With extrapolation, a 20 ton (warm blooded) dino would have probably then have eaten around 1200-1500 lbs of meat at a meal and the 100 ton sea carnivore, which in the book kills the land carnivore (and presumably eats at least part of it before smaller sea scavengers have their way) probably could eat about 4000 lbs or more, but not as much proportionally (to its size) as the land carnivore since the sea monster had to be cold blooded.So (paleontologist-ly speaking) T Rex probably made up about .01% (or so) of its animal population, couldn't support much more then that population in wide open N. America and Canada land area what did these giant meat eaters in the book possible survive on in only a 314 sq mile land mass?The only prey animals described in the book were smaller critters (perhaps Protoceratops?), and these were too small and infrequent to provide meals for the giant meat eaters described in the book.We know from the fossil record in New Mexico that at least one predatory dino, Coelophysis Beuri was cannibalistic, but if the predators in the book had been cannibalistic over such a small area as 314 sq miles, how did any survive to reproduce?Seems like lots of bad research and science to me.
