dinosaur fasting ecology



Many paleontologists are interested in dinosaur feeding. This is typical
of a consumptionist society. Where overweight is a problem, people look at
dinosaurs and think: hey, they could eat much more than me and still were
attractive!

But some mysteries of dinosaur ecology can be explained only by their
fasting. How could they thrive in apparently arid areas?  Large animal can
build up enormous fat reserves and survive in situations where thinner one
can not.

Why hardosaurs nested in colonies, like birds? At first, it is ecological
impossibility. Bird colonies are located in places inaccessible to
predators: on treetops, cliffs, islands or swamps. Hardosaurs could not
hide so easily. Birds have short nesting season, so predators cannot
eat all the young. Hardosaurs had much longer nesting seasons. Most birds
can fly, so colony can gather food over the big area. Hardosaurs could
not. The only explanation is, that female hardosaurs walked into most
inaccessible places, like deserts or higher ground on the plain which
soon would be flooded, nested and fed young all the time powered by their
fat reserves. This nesting festival would take place every several years.

Galapagos tortoises can fast up to one year, and Nile crocodiles and polar
bears for several months. If one scales this up, large sauropods might
survive in the barren desert, if every 2-10 years there was a rainy
season when animals fed and bred.
