27 04 2021, 18:24:22 - New duckbilled dinosaur discovered in Japan

An international team of paleontologists has identified a new genus and species of hadrosaur or duck-billed dinosaur, Yamatosaurus izanagii, on one of Japan's southern islands. The fossilized discovery yields new information about hadrosaur migration, suggesting that the herbivors migrated from Asia to North America instead of vice versa. The discovery also illustrates an evolutionary step as the giant creatures evolved from walking upright to walking on all fours.

 

22 04 2021, 16:28:36 - Fat-footed tyrannosaur parents could not keep up with their skinnier adolescent offspring

New research suggests juvenile tyrannosaurs were slenderer and relatively faster for their body size compared to their multi-ton parents.

 

16 04 2021, 18:01:10 - Tiny cat-sized stegosaur leaves its mark

A single footprint left by a cat-sized dinosaur around 100 million years ago has been discovered in China by an international team of palaeontologists.

 

15 04 2021, 20:26:23 - How many T. rexes were there? Billions

With fossils few and far between, paleontologists have shied away from estimating the size of extinct populations. But scientists decided to try, focusing on the North American predator T. rex. Using data from the latest fossil analyses, they concluded that some 20,000 adults likely roamed the continent at any one time, from Mexico to Canada. The species survived for perhaps 2.5 million years, which means that about 2.5 billion lived and died overall.

 

02 04 2021, 15:59:49 - How the Chicxulub impactor gave rise to modern rainforests

The asteroid that took out the dinosaurs left the planet in darkness. What did rainforests in South America look like before the impact, and how did they change as a result?

 

31 03 2021, 03:09:56 - The 'one who causes fear' - new meat-eating predator discovered

Superbly preserved braincase of this new species is an important find - it suggests there was a greater diversity and abundance of abelisaurids late in dinosaurs' era than previously thought.

 

17 03 2021, 02:46:45 - How life on land recovered after 'The Great Dying'

A new study shows in detail how life recovered from 'The Great Dying' in comparison to two smaller extinction events. The international study team showed for the first time that this mass extinction was harsher than other events due to a major collapse in diversity. Ultimately, characterizing communities -- especially those that recovered successfully -- provides valuable insights into how modern species might fare as humans push the planet to the brink.

 

11 03 2021, 21:27:24 - Paleontology: Microscope helps with dinosaur puzzle

Fossil sites sometimes resemble a living room table on which half a dozen different jigsaw puzzles have been dumped: It is often difficult to say which bone belongs to which animal. Researchers have now presented a method that allows a more certain answer to this question.

 

09 03 2021, 17:43:54 - Younger Tyrannosaurus Rex bites were less ferocious than their adult counterparts

By closely examining the jaw mechanics of juvenile and adult tyrannosaurids, some of the fiercest dinosaurs to inhabit earth, scientists have uncovered differences in how they bit into their prey.

 

03 03 2021, 20:24:37 - Prehistoric killing machine exposed

3D imaging of the dinocephalian, Anteosaurus, shows that this massive premammalian reptile that grew to the size of a full-grown hippopotamus, was a highly agile killing machine, and not a slow stodgy scavenger as previously believed.

 

03 03 2021, 03:20:07 - Cutting-edge analysis of prehistoric teeth sheds new light on the diets of lizards and snakes

New research has revealed that the diets of early lizards and snakes, which lived alongside dinosaurs around 100 million years ago, were more varied and advanced than previously thought.

 

26 02 2021, 18:13:06 - Pioneering prehistoric landscape reconstruction reveals early dinosaurs lived on tropical islands

A new study using leading edge technology has shed surprising light on the ancient habitat where some of the first dinosaurs roamed in the UK around 200 million years ago.

 

26 02 2021, 16:38:22 - Dinosaur species: 'Everyone's unique'

'Everyone's unique' is a popular maxim. All people are equal, but there are of course individual differences. This was no different with dinosaurs. A study has now revealed that the variability of Plateosaurus trossingensis was much greater than previously assumed. The paleontologists examined a total of 14 complete skulls of this species, eight of which they described for the first time.

 

25 02 2021, 20:39:20 - Did teenage 'tyrants' outcompete other dinosaurs?

Paleo-ecologists have demonstrated that the offspring of enormous carnivorous dinosaurs, such as Tyrannosaurus rex may have fundamentally re-shaped their communities by out-competing smaller rival species.

 

24 02 2021, 16:08:49 - New fossil discovery illuminates the lives of the earliest primates

A new fossil discovery is central to primate ancestry and adds to our understanding of how life on land recovered after the Cretaceous-Paleogene extinction event 66 million years ago that wiped out all dinosaurs, except for birds.

 

19 02 2021, 14:38:48 - Quartz crystals in the stomach of fossil bird complicates the mystery of its diet

The fossil of a bird that lived alongside the dinosaurs was found with some sort of rocks in its stomach. Previously, researchers thought that these rocks were swallowed on purpose to help clean its stomach, like modern birds of prey do, giving a hint at its diet. But in a new study, scientists discovered that these rocks are quartz crystals that likely formed after the bird died -- its diet is still a mystery.

 

16 02 2021, 17:51:10 - Enormous ancient fish discovered by accident

Fossilised remains of a fish that grew as big as a great white shark and the largest of its type ever found have been discovered by accident.

 

15 02 2021, 22:02:30 - Carbon dioxide dip may have helped dinosaurs walk from South America to Greenland

A new study identifies a climate phenomenon that may have helped sauropodomorphs spread northward across the Pangea supercontinent.

 

27 01 2021, 14:39:01 - New light shed on behavior of giant carnivorous dinosaur Spinosaurus

New research has reignited the debate around the behavior of the giant dinosaur Spinosaurus.

 

25 01 2021, 15:43:43 - New skull of tube-crested dinosaur reveals evolution of bizarre crest

The first new skull discovered in nearly a century from a rare species of the iconic, tube-crested dinosaur Parasaurolophus was announced today. The exquisite preservation of the skull, especially the bizarre tube-shaped nasal passage, finally revealed the structure of the crest after decades of disagreement.

 

19 01 2021, 17:44:33 - All-purpose dinosaur opening reconstructed

Researchers have described in detail a dinosaur's cloacal or vent -- the all-purpose opening used for defecation, urination and breeding.

 

14 01 2021, 17:19:18 - Spectacular fossil discovery: 150 million-year-old shark was one of the largest of its time

A team led by Sebastian Stumpf from the University of Vienna describes an well-preserved skeleton of the ancient shark Asteracanthus. This rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago. The almost complete skeleton shows that Asteracanthus was two-and-a-half meters long, which makes this ancient shark one of the largest of its time.

 

07 01 2021, 14:37:51 - Why crocodiles have changed so little since the age of the dinosaurs

New research explains how a 'stop-start' pattern of evolution, governed by environmental change, could explain why crocodiles have changed so little since the age of the dinosaurs.

 

16 12 2020, 17:32:40 - When dinosaurs disappeared, forests thrived

To understand how specific ecosystems were affected by a large asteroid impact that led to the mass extinction of dinosaurs, a team of scientists has analyzed the microscopic remains of plants from this period. They found that local plant communities and ecosystems experienced a long-term shift towards fewer aquatic plants and an increase in terrestrial plants, including trees such as birches and elms. Changes in rainfall patterns during the extinction event were relatively minor and short-lived.

 

15 12 2020, 01:23:49 - New dinosaur showed descendants how to dress to impress

Scientists have found the most elaborately dressed-to-impress dinosaur ever described and say it sheds new light on how birds such as peacocks inherited their ability to show off.

 

14 12 2020, 15:01:43 - Unexpected insights into early dinosaur's brain, eating habits and agility

A pioneering reconstruction of the brain belonging to one of the earliest dinosaurs to roam the Earth has shed new light on its possible diet and ability to move fast.

 

25 11 2020, 01:05:27 - T. rex had huge growth spurts, but other dinos grew slow and steady

By cutting into dinosaur bones and analyzing the growth lines, a team of researchers discovered that T. rex and its closest relatives got big thanks to a huge growth spurt in adolescence, while its more distant cousins kept on growing a little bit every year throughout their lives.

 

24 11 2020, 17:13:32 - Only dinosaurs found in ireland described for the first time

The only dinosaur bones ever found on the island of Ireland have been formally confirmed for the first time by a team of experts. The two fossils are from two different dinosaurs, a four-legged plant-eater called Scelidosaurus and a two-legged meat-eater similar to Sarcosaurus.

 

18 11 2020, 01:26:26 - New analysis refutes claim that dinosaurs were in decline before asteroid hit

New research suggests that dinosaurs were not in decline before the asteroid hit. The study contradicts previous theories and concludes that had the impact not occurred dinosaurs might have continued to be the dominant group of land animals.

 

06 11 2020, 18:33:13 - Baby dinosaurs were 'little adults'

Paleontologists have described for the first time an almost complete skeleton of a juvenile Plateosaurus and discovered that it looked very similar to its parents even at a young age. That could have important implications for how the young animals lived and moved around. The young Plateosaurus, nicknamed 'Fabian', was discovered in 2015 at the Frick fossil site in Switzerland.
