The Giganotosaurus and Spinosaurus masses (14 and 21 t) were obtained in a very questionable manner from an allometric regression that plots skull legnth vs body mass, without considering the proportions of the postcrania (the regression of Therrein and Hendersson 2007 had many values plotted wrong as well), and some animals like Pentaceratops, Camarasaurus, or Mamenchisaurus are ridiculously oversized when compared to the real specimens. Sometimes it feels like they are picked from the highest estimate posible listed in english wikipedia, and other times they feel outright made up.įor example the mass estimate for Tyrannosaurus is 18 t that estimate is obtained from a grotesquely obese model from Hutchinson et al 2011 and one can't seriously argue the maximum model is as likely as the minimum for a healthy predator.
One thing that every paleo enthusiast will notice is that the scaling and the vital statistics of the dinosaurs feel very rushed and not very throughly studied. Anyway, here are all the dinosaurs in the recently released Jurassic World Evolution game, a tycoon similator in which you attempt to create your own Jurassic world. I have had this on my computer for a long time but somehow didn't find the time for the upload.
