All rights reserved. For the first few months of the year, I would watch with glee as my mom carefully cracked our weekend breakfast eggs to leave only a dime-size hole on one end, and I relished playing with the food dyes and confetti on assembly day. But of course, nothing compared to the satisfying crunch as I smashed one of those carefully made eggs over the head of a laughing aunt, uncle, or cousin on Easter morning. Humans have a long history of weaving colorful bird eggs into our cultural traditions. And as with many things that bring me joy, I can thank dinosaurs for that. Modern birds are the last living descendants of dinosaurs, which also laid eggs in a fabulous variety of shapes and colors. According to research on the fossilized pigments from ancient eggs, dinosaurs picked up the habit of making their shells in a rainbow of hues more than million years ago. Perhaps counterintuitively to us, with our limited human perception of color, adding blues and greens and speckles to eggs was a way of making them less visible to predators, our Michael Greshko reported in According to a paper released this week in the journal Nature , fossil eggs from the dinosaurs Protoceratops and Mussaurus pictured above both show chemical traits of being soft rather than calcified.
First Soft-Shelled Dinosaur Egg Fossils Found
An egg of Himeoolithus murakamii left , outlined egg with intact eggshell remains black area middle , and reconstruction of Himeoolithus murakamii and their probable parent dinosaur right. Newswise — Tsukuba, Japan – When most of us think of dinosaurs, we envision large, lumbering beasts, but these giants shared their ecosystems with much smaller dinosaurs, the smaller skeletons of which were generally less likely to be preserved.
The fossilized egg shells of these small dinosaurs can shed light on this lost ecological diversity. The Kamitaki Egg Quarry, found in a red-brown mudstone layer of the Ohyamashimo Formation, deposited in an Early Cretaceous about million years old river flood plain, was carefully and intensively excavated in the winter of , and yielded over egg fossils.

Dinosaur Eggs Fossils. Dinosaur Fossils.
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. According to two studies published in Nature this week, dinosaur eggs may have been, well From the lab to your inbox.

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. The team surveyed the stratum, which dates back million years, between and and found four fossil eggs and over 1, scattered eggshell fragments.
It has confirmed the findings, including the newly discovered one, which has been named Himeoolithus murakamii, can be categorized into four different types. The team said the discovery suggests that various small dinosaurs were nesting together in the area, known as one of the world’s richest Lower Cretaceous fossil egg sites.
Tiny Japanese dinosaur eggs help unscramble Cretaceous ecosystem
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.
Date: June 26, ; Source: University of Tsukuba; Summary: A research team has excavated over eggshell fossils from the Lower Cretaceous.

It can’t be millions of years! Its from a global flood! Eggs have been found all over the world, up to Myr. Some dinosaur embryos have been detected by CAT scans and other Xray techniques. In in Germany, pigments found in dinosaur eggs that they think point to bluegreen eggs.
Soft-shelled dinosaur eggs crack the mystery of missing fossils
Bring the family and learn about how dinosaurs raised their tiny titans! This exhibit features dinosaur eggs and babies! On display in our Changing Exhibits Gallery, this remarkable hands-on exhibit offers an astounding array of authentic dinosaur eggs and nests collected from all over the globe — including those of each of the major plant and meat-eating dinosaur groups. A central feature of the exhibit is a presentation about the discovery of Baby Louie, the nearly complete skeleton of a dinosaur embryo with its bones aligned in the proper position.
Charlie Magovern made this exceptional and rare discovery in when he was carefully cleaning a large block of eggs from China.

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. Zelenitsky, who specializes in dinosaur eggs and nesting sites. It stood to reason that dinosaurs also only laid hard-shelled eggs.
The international research team looked at egg clutches unearthed in Mongolia and Argentina with an unusual thin halo surrounding the fossilized embryos. The Mongolian eggs, which were oval and up to 15 centimetres long, belonged to a horned dinosaur estimated to be between 71 million and 74 million years old.
Boy finds 66-million-year-old dinosaur eggs
The book summarizes and paleontologic expeditions to a spectacular fossil-collecting site in Patagonia where the authors discovered hundreds of eggs laid by foot-long titanosaur dinosaurs on a floodplain of Late Cretaceous age. Some of the eggs contained embryos, and many were found in clutches within nests excavated by the huge sauropods. The exciting find of a skeleton of a probable predator of the titanosaurs is also described.
An innovative format posing the reasoning followed in answering nine questions about the site, its former environment, and its former inhabitants provides an introduction to scientific methodology for younger readers. An especially thought-provoking question discusses the shaky scientific premises and methods used in re-creating living dinosaurs in the movie Jurassic Park.
Color photographs taken in the field and excellent color reconstructions further enhance the book.

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
