Instead of cracking open like a chicken’s egg, some dinosaurs may have emerged from soft-shelled eggs, like turtles or snakes. Despite what movies like Jurassic Park and The Land Before Time may lead you to believe, some dinosaurs may not have cracked open hard-shelled eggs as they emerged into the world. Instead, they may have had a much softer debut.
Eggs of different colors evolved in dinosaurs before the appearance of birds.

Researchers believe they have cracked the mystery of why fossilized eggs of only a few types of dinosaurs have been found.
One of the authors of the study, University of Calgary paleontologist Darla Zelenitsky, said many fossilized eggshells have been found for certain bird-like, meat-eating dinosaurs as well as some long-necked and duck-billed plant-eaters. Eggs of other dinosaurs — especially more primitive species — have been notably absent.
Tiny Japanese dinosaur eggs help unscramble Cretaceous ecosystem
A team of researchers said Tuesday it has discovered the world’s smallest dinosaur egg fossil, measuring about 4. The fossil of the egg, estimated to have weighed only about 10 grams more than million years ago, was found in a stratum dating back to the Early Cretaceous period in Tamba, Hyogo Prefecture, according to the team. The researchers at the University of Tsukuba and the Museum of Nature and Human Activities, Hyogo, among others, who have analyzed the fossil, said it likely belonged to a non-avian small theropod.
Skeletal remains of small dinosaurs are far less common than those of large dinosaurs, such as the Tyrannosaurus, which was also a theropod, and Kohei Tanaka of the University of Tsukuba, a member of the team, said he hopes the discovery will “help shed light on how small dinosaurs reproduced and nested.
Date: June 26, ; Source: University of Tsukuba; Summary: A research team has excavated over eggshell fossils from the Lower Cretaceous.

Finding the answer to the first occupies much of Chiappe and Dingus’s account, as they compare their evidence against similar finds in Spain and the Gobi.
Determining the second affords the authors a chance to discuss newly developed dating techniques, including DNA analysis–which caused overly enthusiastic reporters to announce that the authors were on the brink of cloning sauropods from long-dead embryos. Finally, their reconstruction of the ancient environment of Patagonia offers clues for how the unlucky eggs had come to be buried in prehistoric mud.
A spirited book about how paleontologists make and test hypotheses and go about their fieldwork, this makes a fine addition to any dinosaur buff’s collection. Just days into the excursion, the archeologists discovered the remains of a nesting site for a sauropod, a large, four-legged, thick-necked, vegetarian, semi-aquatic dinosaur. Dating back about 80 million years, the giant rookery was strewn with thousands of broken and unhatched fossilized eggs.
Besides providing science long-sought proof that sauropods were egg-laying creatures, this field of prehistoric eggs also yielded the first fossils of embryonic dinosaur skin. Although the authors furnish detailed geological and paleontological background information, they write without scientific jargon, fortunately for lay readers. Through the mostly conversational narrative, an intriguing story unfolds that offers insights into the mysteries surrounding this astounding archeological find.
Boy finds 66-million-year-old dinosaur eggs
As any child can tell you, dinosaurs, not birds, invented feathers. According to a new scientific report, dinosaurs also invented — or, if you want to get technical, first evolved — eggs of different colors. Birds did not evolve their egg colors on their own, but inherited the ability from non-avian dinosaurs. Until a few years ago, the color of dinosaur eggs was unknown. Other reptiles, like snakes and turtles, usually lay off-white eggs. Then, in , Jasmina Wiemann and colleagues reported the presence of two pigments, one blue-green and one red, in oviraptor eggs.

The dinosaur egg facts below will help you learn about what are dinosaur eggs, how we find dinosaur eggs today, the different types of dinosaur eggs, what dinosaur eggs were like and other dinosaur egg related facts.
As modern crocodilians and birds lay hard-shelled eggs, this eggshell type has been inferred for non-avian dinosaurs. Known dinosaur eggshells.
Four college students discovered rare dinosaur eggs during a walk through Pingxiang City in the Jiangxi Province of southern China. The finding was made last Saturday and reported to a local museum, where the eggs are now currently being held. Amazing footage shows six fossilised dinosaur eggs of different sizes, all covered in red mud. Experts from the Chinese Academy of Science studied the fossils, and confirmed them to be that of dinosaur eggs.
The fossils date back to the late Cretaceous Period, which span from the end of the Jurassic Period million years ago to the beginning of the Palaeocene Period 66 million years ago. This is not the first time dinosaur discoveries have been made in the Pingxiang region, with several dinosaur skeleton fossils being found in September Meanwhile in other discoveries, a closely related dinosaur to the Tyrannosaurus rex has finally been given a named after a year-old archaeology enthusiast first discovered its fossil 20 years ago.
The newly named dinosaur, Suskityrannus hazelae, was dug out by high school student Sterling Nesbitt during a dig in New Mexico in Dr Nesbitt, now an assistant professor at the Virginia Tech College of Science, led an international collaboration of scientists to classify the dinosaur. Palaeontologists are now certain the Suskityrannus was a smaller cousin of the Tyrannosaurus rex, whose Latin name means King. Unfortunately for the Suskityrannus, the dinosaur was barely taller than an adult Great Dane dog.
A dinosaur egg fossil with an eggshell was also discovered on a building site in April

Dinosaur eggs, bones and marine fossils, dating back to the Cretaceous period — which ended 65 million years ago — are being smuggled out from the Manawar tribal belt, about km from here. An investigation conducted by Hindustan Times, in collaboration with some amateur explorers, revealed that the smugglers were using some galleries in Pune to secretly reach the global buyer. Manawar drew international attention after dinosaur eggs and nesting sites were spotted here for the first time in February , by Mangal Panchayatan Parishad an organization of amateur explorers.
Some even used them as shivlingas, installing them in temples and offering poojas.
A paper published Wednesday in the journal Nature suggests eggs long-necked dinosaur called Mussaurus and date back million years.
Until recently, paleontologists have used dinosaur bones, skeletons, footprints, and trackways to study these extinct creatures, which continue to fascinate children and adults alike. Now, new discoveries of fossil dinosaur eggs, nests, and even embryos are providing a new avenue of investigation for scientists who seek not only information on biological relationships, but also on the behavior of these animals, and are shedding new light on intriguing questions paleontologists have been pondering for over a century.
The answer to the first question is a matter of opinion; visitors can come and see for themselves. The answers to the other questions are a matter of scientific debate; the exhibit presents some of the evidence for these ideas, and visitors are invited to form their own opinion. The science of dinosaur eggs and embryos is still relatively new.
Compared to bones, dinosaur eggs are much less frequently found and more difficult to study. Dinosaur eggs are known from all continents except Australia and Antarctica. In recent years, egg finds in Montana and China, primarily of Late Cretaceous Age million to 65 million years ago have increased dramatically the number of eggs known.
Whether dinosaur embryos are preserved within those fossil eggshells, and whether the bones can be successfully exposed and studied, are difficulties that paleontologists face. Scientists classify eggs of different animals according to size and shape of the egg, thickness and texture of the eggshell, and according to the biocrystalline structure of the eggshell. This is determined by examining thin sections of eggshell under a microscope with polarized light and a scanning electron microscope for more detail.
Broad similarities and differences in structure have permitted scientists to group eggshell into six basic types and a number of subtypes. Based on the characteristics noted above, dinosaur eggs are divided into several groups, which are believed to correspond to major groups of dinosaurs:.
