A female Seismosaurus, for instance, may have laid as many as 20 or 30 eggs at a time (despite what you may think, the eggs of 50-ton sauropods weren’t any bigger than bowling balls, and often significantly smaller). Why did dinosaurs lay so many eggs?

How long did Maiasaura live with their parents?

However, the fossil evidence shows that Maiasaura hatchlings and juveniles continued to live alongside their parents for years, and presumably stayed with the herd well into adulthood (at which point they added to it with their own set of hatchlings). How long did it take for a newborn Maiasaura to attain its full adult size?

How did the Maiasaura walk?

Maiasaura were herbivorous. They were capable of walking both on two ( bipedal) or four ( quadrupedal) legs. Studies of the stress patterns of healed bones show that young juveniles under four years old walked mainly bipedal, switching to a mainly quadrupedal style of walking when they grew larger.

Were dinosaurs born on land or in nests?

There is no doubt here that dinosaurs were born on land from hard-shelled eggs. While most people like to believe that all birds hatch in nests above ground, there are a number of birds which do lay their eggs in nests on land – much like the image we have of dinosaurs from recovered nesting sites.

Could Seismosaurus’heart have been stronger than its neck?

The (indisputably) extreme length of Seismosaurus’ neck—at 30 to 40 feet, it was much longer than the necks of most other sauropod genera, with the possible exception of the Asian Mamenchisaurus —raises an interesting question: could this dinosaur’s heart possibly have been strong enough to pump blood all the way to the top of its head?
