Scientific errors

  • On page 209, on the family tree, Pteranodon is incorrectly placed in the crocodilian family branch.
  • Also in the family tree, Nothosaurus is placed on a separate branch from the one labeled Nothosaurs.
  • The family tree also claims that the carnivores descended from the creodonts. However, this is a grossly outdated theory. Rather, the carnivores more likely descended from the miacids.
  • The family tree shows that apes first appeared in the Oligocene Epoch, while the oldest known ape, Proconsul, dates back to the later Miocene Epoch.
  • Cameroceras is repeatedly misspelled as "Cameraceras". This is probably just an accident.
  • Coelophysis is repeatedly misclassified as a Coelurosaur, while it was actually a much more primitive dinosaur - a coelophysid.
  • On page 64, it is said that nothosaurs laid eggs. However, it is now generally agreed that they gave live birrth like their relatives, the plesiosaurs.
  • On page 65, Cymbospondylus is dubbed the largest ichthyosaur of all time. In fact, the creature was not even half the size of Shastsaurus,[1] which is the largest known marine reptile. Interestingly, the book version of Chased by Sea Monsters states that the largest ichthyosaur is either Shonisaurus or an undescribed genus.
  • On page 90, Eustreptospondylus and Megalosaurus are said to be carnosaurs, while they are close relatives of the Spinosaurids. However, a study of the megalosauroids (including both the megalosaurids and spinosaurids) in 2019 may prove this theory.[1]
  • On page 108, ’’Ornithocheirus’’ is mispronounced as (AWN-ith-oh-kyrus).
  • On page 112, Leaellynasaura is said to be an ornithopod. However, it may have been a more primitive ornithischian dinosaur that does not fit in any of the known families. This is however, controversial.
  • On page 127, it is said that there is no evidence for Velociraptor having feathers. However, quill knobs have been found in association with the creature's skeleton, showing that its arms, at least, were feathered. However, this discovery was made after the book was published.
  • On page 137, it is said that Tyrannosaurus means "terrible reptile". However, this is what the term dinosaur means. Tyrannosaurus means "tyrant lizard".
  • On page 138, it is said that Torosaurus means "bull reptile". However, this is a common misconception. It actually means "perforated reptile".
  • On page 188, Smilodon is said to have died out 100,000 years ago. However, it is known to have survived until 11,000 years ago.[4][5]
  • On page 190, the closest living relative to Phorusrhacos is said to be the secretary bird. That would actually be the seriema.[6]
  • On page 196, Megaloceros is said to reach antlerspan up to 3 meters (10 ft.) while, in fact, specimens with 4 meters (13.1 ft.) are not uncommon.
  • On page 197, the Cave Lion is depicted with a much shorter tail than it had in real life.
  • On page 201, it is said that a population of pygmy mammoths survived on an island off the east coast of Russia until about 6,000 years ago. In fact, this time estimate is only accurate about the population on the Alaskan Saint Paul island than the real last sanctuary, the Wrangel Island, where the most recent remains are as young as 3,700 years old.
  • In the silhouette of Tarbosaurus the human is smaller than the one of Tyrannosaurus rex in real life they would be the same size. It was probably just a accident. 
  • The size comparison images of some animals are erroneous, such as Meganeura, Ornitholestes (both too big), Megatherium and Megaloceros (both too small). Also, the silhouette used for Tarbosaurus(actually a stock image that has been used in older books) depicts the animal standing in a like a modern kangaroo, instead of with its backbone parallel to the ground. Also, an old stock image of Eryops was used for the size comparison model for Proterogyrinus, although Eryops had a more rounded skull than Proterogyrinus. Lastly, the silhouette of Indricotherium is actually that of a calf, as you can tell by its proportions.
  • On the Velociraptor page, it is mentioned that Jurassic Park came out in 1992, when it actually came out a year later.
