Discover some amazing dinosaur remains

From tiny trilobites to immense dinosaurs, a wonderful array of creatures has lived on Earth over the past 4 billion years. Deep in the earth around you are the sealed remains of past life. Paleontologists work to show these fossils, which can be many different shapes, sizes, and colors. Usually, fossils are the teeth, bones, or shells of olden animals, but sometimes we find out something even rarer, like fossilized poop.

Fossilized feces are called coprolites, meaning “dung stones.” Coprolites frequently seize clues to an animal’s meal, the atmosphere in which the animal lived, and more. Dino poop — along with coprolites from other dead animals — can tell notable stories about creatures that lived millions of years ago.

 By investigative fossil feces, along with teeth, bones, and sealed stomach contents, scientists can part together how dinosaur carnivores, omnivores, and herbivores ate and digested their meals.

Did Dinosaurs Poop? Is a brand new hands-on exhibition for children opening Sept. 14 at the Museum of the Earth? Considered mainly for families with children ages 4 to 10 but fun for all ages, the exhibition presents a fun and multicolored approach to knowledge about fossils and dinosaur diets.

The museum will celebrate Family Day from 10 a.m. to 1 p.m. Sept. 15 with fun practical activities and two showings at 10:30 a.m. and 1 p.m. of WSKG’s “Dinosaur coach: Every fossil Poops” event.

Fossils of dicynodont exposed on each continent

Dinosaur Fossils
Fossils discovered on a Tasmanian beach have established the survival in Australia of the dicynodont – an odd-looking species that lived 30 million years previous to the dinosaur – proving it existed on all continents.

The fossils were established by a pair strolling on a seaside on the Tasman Peninsula. The plant-eating animals, about the size of a cow, lived about 250 million years ago and became destroyed about 20 million years ago.

Complete specimens of the dicynodont have been establishing in India and South Africa. The detection of the two skull pieces found in Tasmania has enabled scientists to verify that the creature lived in Australia. The only other proof was a fossil found in Queensland in 1983.

A paleontologist of Queensland Museum, Dr Andrew Rozefelds said the "strange-looking beast” may have survived longer in Australia than on other continents.

Australia is an island continent and perhaps some things like the monotremes, like the platypus and the echidna, survived here as elsewhere in the earth they became extinct.

Older fossils resolve secrecy of earliest bird extinction

Dinosaur fossil
The meteorite crash that coincided with the vanishing of the dinosaurs 65 million years ago also saw a fast refuse in prehistoric bird species.


Only a little bird groups survived through the accumulation death, from which all contemporary birds are descended.

There has been a long standing argue over the destiny of the earliest "archaic" birds, which first evolved about 200 million years ago.

Whether their populations declined gradually towards the end of the Cretaceous time, or whether they suffered unexpected accumulation extinction at the Cretaceous-Tertiary (K-T) boundary is unsettled, owing to contradictory evidence.

DNA studies have attempted to date the source of contemporary birds; some propose that they appeared before the extermination of dinosaurs, with big facts of them existing through the extermination affair.

Bird bones are very hard to protect as fossils as they are little and glow, and easily injured or swept away in rivers.

But the new investigate, headed by Dr Longrich, have made use of fragmentary bird fossils composed up to 100 years ago, from locations across North America.

Long-ignored fossil determined to be brand new species of horned dinosaur

Dinosaur fossil
A set of dinosaur bones unearthed in Alberta in 1916 and left unexamined on a shelf in Britain's Natural History Museum for over ninety years has yielded a sudden and significant discovery: a brand new species of horned dinosaur that is forcing scientists to review the dividing line between two huge, plant-eating beasts associated with the well-known triceratops. The 75-million-year-old skull fragments from many people of the newly identified species were found during a first World War-era dig in an exceedingly dinosaur bone bed southeast of Calgary, inside or just outside of today's Dinosaur Provincial Park.

The specimens were collected by the renowned American fossil hunter Charles H. Sternberg and his son Levi.

The family, which later was instrumental in the creation of Dinosaur Provincial Park, created several pioneering paleontologists who went on to distinguished careers in Canadian science, including Levi with the Royal Ontario Museum and his brothers George at the University of Alberta and Charles M. Sternberg of the longer term Canadian Museum of Nature.

The Alberta bones delivered to Britain ninety five years ago were promptly dismissed as indecipherable "rubbish" by the London museum's geology curator. In 2000, when seeing photos of the fossils that suggested they could in fact, represent a brand new species, Canadian paleontologist Michael Ryan —currently curator of vertebrate paleontology at the Cleveland Museum of Natural History — visited the British museum solely to find that the bone fragments had been misplaced.

More recently, American dinosaur professional Andrew Farke contacted Ryan to mention that he'd found the Sternberg specimens and agreed that they marked an important but long-overlooked insight into the evolution of horned dinosaurs.
