Soft-shelled dinosaur eggs crack the mystery of missing fossils

One study found evidence that some of the earliest dinosaurs laid soft-shelled eggs, and not eggs with hard shells as was previously thought. The second discovery is another soft-shelled egg that researchers have attributed to a kind of giant marine reptile called a mosasaur. The new evidence that some dinosaurs and their extinct reptilian contemporaries laid eggs without hard shells helps explain the rarity of eggs in the first half of the fossil record, according to the Times. Soft shells tend to rot away quickly, which would have made it less likely for them to fossilize. Both finds may have implications for the reproductive evolution of dinosaurs and ancient reptiles. It was a fossil the size of a football that had a crinkled exterior that made it look deflated. But when paleontologist Julia Clarke of the University of Texas at Austin saw its rumpled surface, she knew just what she was looking at. It was a giant, soft-shelled egg, and it was also 66 million years old, the researchers report this week in Nature. No fossilized embryo or hatchling was available to positively identify what creature produced it.

Dinosaur Eggs and Babies

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.

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. 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.

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.

That puts Himeoolithus murakamii among the smallest non-avian theropod eggs reported to date. These tiny eggs were notably elongated in.

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. Fossilized dinosaur eggs have been found elsewhere, including Spain and Mongolia, but many of them are 5 to 7 cm in length and weigh about 30 g.

By Jack J. June 24, at pm. Studies of fossilized embryos from two kinds of dinosaurs, one from early in dinosaur history and the other living about million years later, reveal the eggs were enclosed by soft shells , paleontologists report online June 17 in Nature. The discovery marks the first time scientists have identified soft-shelled dinosaur eggs. Further analyses of these and other dinosaur eggs suggest that hard eggshells evolved independently for each of the three main dinosaur lineages: the long-necked sauropods, plant-eating ornithischians and fierce theropods.

Until now, paleontologists thought that all dinosaurs had hard, mineralized eggshells.

Eggs of different colors evolved in dinosaurs before the appearance of birds.

Dinosaur eggs were laid by female dinosaurs and contain a developing dinosaur embryo. Dinosaur eggs vary in shape, size, color and texture.

Researchers have discovered that some dinosaur eggs were a blush-green color. The first fossilized dinosaur egg was discovered in by French amateur naturalist Jean-Jacques Poech in France.

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. Get the latest science stories from CNET every week. Previous eggs in the fossil record mostly come from late in the dinosaur timeline, closer to their ultimate end some 66 million years ago. We’ve got fossilized bones of creatures dating back million years, but no eggs. So why weren’t their eggs preserved? Norell believes his team have answered that question in their study finding, despite conjecture dinosaurs produce hard-shelled eggs, there is fossilized evidence confirming some types of dinosaur, namely, Protoceratops and Mussaurus , produced soft-shelled eggs.

The creatures buried and incubated these eggs in moist soil, like some reptiles do today. Soft-shelled eggs aren’t as exquisitely preserved as their hard-shelled counterparts — they disintegrate before given a chance to fossilize — leaving a gap in the fossil record.
