Whether you are a kid, student, or teacher, you'll find a rich set of dinosaur names, pictures, and facts here. This site is built with PaleoDB, a scientific database assembled by hundreds of paleontologists over the past two decades.
Please can someone post a picture of the red dinosaur? I'm very eager to get this plan but Noone has posted what it actually looks like. The Google has been no help on the appearance of the dinosaur. please and thank you
A team of Argentinean and U.S. scientists has found fossils of a duck-billed dinosaur, along with remains of Antarctica's most ancient bird and an array of giant marine reptiles, on Vega Island off the eastern side of the Antarctic Peninsula.
The tooth of a duck-billed dinosaur, or hadrosaur, was found in sands about 66-67 million years old, from the Cretaceous period (about 1-2 million years before the asteroid impact that contributed to the extinction of the dinosaurs). The team that found the fossils is headed by Sergio Marenssi of the Instituto Antartico Argentino and Judd Case of St. Mary's College, California.
"This is the first duck-billed dinosaur to be found outside the Americas," said Mike Woodburne, University of California-Riverside paleontologist who is part of the project. "This gives us more support for the idea of a land bridge between South America and Antarctica at that time." The land bridge was used not only by dinosaurs but probably also by marsupial mammals dispersing from the Americas to Australia via Antarctica.
The hadrosaurs are a distinctive group of American dinosaurs, known for fancy crests on their skulls with networks of passageways that may have been used for vocalization and that may suggest the animals were social. Some stood perhaps 20 feet tall.
The region around Vega Island is extremely rich in both terrestrial and marine fossils, and the only such fossil trove in Antarctica to span the boundary of the Cretaceous and Tertiary periods, the time when the dinosaurs were wiped out.
The teeth on T. rex and other big theropods were likely covered by scaly lips, concludes a study published Thursday in the journal Science. The dinosaur's teeth didn't stick out when its mouth was closed, and even in a wide open bite, you might just see the tips, the scientists found.
Recent depictions show big teeth jutting out of the dinosaurs' jaws, even when closed. Some thought the predators' teeth were just too big to fit in their mouths, said study author Thomas Cullen, a paleontologist at Auburn University in Alabama.
When researchers compared skulls from dinosaurs and living reptiles, though, they found this wasn't the case. Some large monitor lizards actually have bigger teeth than T. rex compared to their skull size, and can still fit them under a set of scaly lips, Cullen said.
It's not the first time our depictions of dinosaurs have been called into question: Other research has shown that T. rex was more hunched over than we used to think, and that fierce velociraptors probably sported feathers. Most of what we know about dinosaurs comes from their bones, but it can be harder to get clear answers about soft tissues like skin, which usually aren't preserved as fossils.
This page is mainly for reviewing the accuracy of dinosaur life restorations (usually by the artists themselves, but anyone who wants an image scrutinized is welcome to post it for review). Any other image, such as size comparisons or photos of skeletal mounts, can also be posted here to review their accuracy.
If you want to submit dinosaur images for accuracy review, place them here as well as links to what you used as references. If you want to participate as reviewer, you can put the page on your watchlist. New images of any type can also be requested by including "Request:" in the section title; if submitted, such an image will thereafter be reviewed here. Sections are archived automatically after some time when a discussion stalls, to encourage speedy responses from both artists and reviewers. It is allowed to revive sections if they have been archived before being resolved, unlike regular talk page archives.
Images that have been deemed inaccurate should be tagged with the Wikimedia Commons template "Inaccurate paleoart"[5] (which automatically adds the "Inaccurate paleoart" category[6]), so they can be prevented from being used and easily located for correction. User created images are not considered original research, per WP:OI and WP:PERTINENCE[a], but it is appreciated if sources used are listed in file descriptions (this is often requested during WP:Featured Article reviews).

Here is a simplified setup to demonstrate. I want to apply the flower image to the rectangle with the 2D pieces, then the pieces should cut up the flower image and show the correct parts of the image on the assembled version of the dinosaur in the new position.
Here is a flower picture projected onto the shapes in the dinosaur model, then each piece made to be thicker, and made into a group. The image is floating above the pieces, and scaled to be slightly bigger than the area occupied by the pieces.

A long-standing mystery in paleontology is why we have discovered thousands of eggs from some types of dinosaurs, such as the duck-billed hadrosaurs, but none at all from other types of dinosaurs, such as the armored stegosaurs. For more than a century, most paleontologists hypothesized that all dinosaurs laid hard-shelled eggs. This assumption seemed like a safe one because the closest living relatives of dinosaurs, crocodilians and birds, also lay hard-shelled eggs. In 2020, however, that assumption was completely overturned, opening an exciting new realm of research on dinosaur reproduction.
The road to our current understanding of dinosaur nesting began long ago. When the first species of dinosaur, Megalosaurus bucklandi, was named in 1821, paleontologists knew almost nothing about how dinosaurs reproduced. In 1921, the first major clue emerged: Acclaimed fossil hunter Roy Chapman Andrews discovered intact dinosaur nests in Mongolia. In fact, dinosaur eggs had already been found in France in 1859, but were mistakenly thought to belong to giant birds at the time.
People are never going to see a live nonavian dinosaur, but thanks to discoveries like these we are now learning previously unimaginable details about dinosaur family life. Dinosaurs were remarkable creatures. Although we tend to emphasize the shared features of dinosaurs and birds, dinosaurs in fact possessed a mixture of birdlike traits, reptilian traits, and unique traits not seen in either group. In the case of Protoceratops, finding out that its eggs were soft was completely unexpected since both birds and crocodilians lay hard-shelled eggs. This discovery also unlocked new details of Protoceratops nesting behavior. Soft-shelled eggs are more sensitive to the environment, because they lose moisture easily in dry conditions. In addition, parents could not sit directly on top of them without risking a crushed shell. Given these limitations, Protoceratops likely buried its eggs in moist sediment and left them to be incubated by external heat sources such as decaying plants or sunlight.
As Norell and Wiemann studied more eggs from species on different branches of the dinosaur family tree, a startling implication emerged: The very first dinosaur egg was probably soft as well. Norell and Wiemann observed that soft eggs were laid by the ancestors of the giant long-necked sauropod dinosaurs, as well as by the winged pterosaurs, which are considered by most paleontologists to be close relatives of dinosaurs. This finding suggests that the earliest dinosaurs were limited to moist nesting environments. Other groups of dinosaurs evolved a hard calcite shell that locked in moisture and allowed them to nest in a wider range of environments. This development would have offered a major advantage, and at least three separate dinosaur lineages evolved hard-shelled eggs independently: theropods, sauropods, and hadrosaurs.
Using mass spectroscopy, Wiemann identified pigments called protoporphyrin and biliverdin in the eggs of oviraptorids and other dinosaurs. These two versatile pigments combine in different ways to make up the palette of colors found in modern bird eggs. Examining chemical signatures in layers of eggshell, Wiemann reconstructed the color patterns of dozens of dinosaur eggs. Her work yielded startling results that showed that dinosaur egg morphology and nesting behavior had diversified prolifically from the simple buried nests full of plain, soft-shelled eggs that Protoceratops had left behind.
The fact that eggshell pigments are detected only in theropods provides another piece of evidence (in addition to features like feathers and a wishbone) that this group of dinosaurs gave rise to modern birds. Birds are the only living amniotes that lay colored eggs, making it likely that eggshell pigments evolved a single time in an ancestor of birds and advanced theropods.
