The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline. Doing so allowed them to determined that the Protoceratops and Mussaurus eggs were indeed non-biomineralized - not hard or calcified  - and, therefore, leathery and soft. With data on the chemical composition and mechanical properties of eggshells from 112 other extinct and living relatives, the researchers then constructed a 'supertree' to track the evolution of the egg shell structure and properties through time. The ceratopsian then feeds on the stuff inside, a slimy pulp, which contains the seeds of the zlatkopalm. The giant egg has a soft shell.

So I'll support the nill solution. The structure is very similar to transparent, quick-hatching eggs laid by some snakes and lizards today, he said. Become a Study.com member to unlock this Also, egg laying would make there be gaps in the defense unless the humans told the ceratopsians something along these lines: ... the power of ceratopsian defense isn't so much about the size of the individual as the ability of the herd to act as a group and instinctively adopt a defensive posture capable of deterring one of more carnosaurs. We give our hens a break during the winter. ... protoceratops guarding its egs from a raptor two dinosaurs one a velociraptor the other ceratopsian like triceratops Digital render of a dinosaur protoceratops isolated on white background. 3. This fossilized egg was laid by Mussaurus, a long-necked, plant-eating dinosaur that grew to 20 feet in length and lived between 227 and 208.5 million years ago in what is now Argentina. 2. Despite its relative strength, the egg is an extremely fragile product and even with the best handling methods, serious losses can result from shell damage. Everyone wonders if T. rex ever battled a Triceratops.The jury is still out on that one but they lived in the same places at the same time so it's not impossible to imagine. Excessive egg laying occurs when a female bird lays more than the normal number of eggs or, more commonly, lays repeated clutches (batches) of eggs, especially in the absence of a mate. This led them to the discovery that hard-shelled, calcified eggs evolved independently at least three times in dinosaurs, and probably developed from an ancestrally soft-shelled type. Aside from its astounding dimensions, the discovery challenges the prevailing idea that such giant marine animals - from a time just before the dinosaur killing asteroid - did not lay eggs.

Other egg-laying stimulatory factors were identified in the atrial gland of an accessory sex organ as an exocrine organ which is located on the reproductive tract, and secreted from the atrial gland into the freshly deposited egg strings of Aplysia, which promoted egg-laying in conspecifics as a pheromone (Nagle et al., 1985; Rothman et al., 1986). But for the most part, they only represent three groups - theropod dinosaurs, which includes modern birds, advanced hadrosaurs like the duck-bill dinosaurs, and advanced sauropods, the long-necked dinosaurs.

New research suggests early dinosaurs laid eggs with soft shells, and mosasaurs—gigantic marine reptiles—did so, too, laying soft-shelled eggs of massive proportions. Its proportions and thin shell - which lacks a crystalline outer layer - suggest the predator was 'ovoviviparous', which means the egg develops inside the mother and hatches as soon as it is laid.

A giant reptile egg unearthed in Antarctica was laid by a 23ft long sea monster 66 million years ago, a new study shows. Because soft egg shells are more sensitive to water loss and offer little protection against mechanical stressors, such as a brooding parent, the researchers propose that they were probably buried in moist soil or sand and then incubated with heat from decomposing plant matter, similar to some reptile eggs today.
