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.
A new study led by researchers from the University of Bristol has shown that not all saber-tooths were fearsome predators.
North America had the T. rex, South America had the Giganotosaurus and Africa the Spinosaurus - now evidence shows Australia had gigantic predatory dinosaurs.
An international research team has been stunned to discover that some species of ancient crocodiles walked on their two hind legs like dinosaurs and measured over three meters in length.
More than 110 million years ago, a lumbering 1,300-kilogram, armour-plated dinosaur ate its last meal, died, and was washed out to sea in what is now northern Alberta. This ancient beast then sank onto its thorny back, churning up mud in the seabed that entombed it--until its fossilized body was discovered in a mine near Fort McMurray in 2011.
The first ever specimen of a pterodactyl, more commonly found in China and Brazil, has been found in the United Kingdom.
A re-analysis of dinosaur skulls from northern Alaska suggests they belong to a genus that lived over a broad latitudinal range extending into the Arctic.
Among dinosaurs of ancient Colorado, scavenging and possibly cannibalism were responses to a resource-scarce environment, according to a study published May 27, 2020 in the open-access journal PLOS ONE by Stephanie Drumheller of the University of Tennessee, Knoxville, and colleagues.
The great white shark is one of the most charismatic, but also one of the most infamous sharks.
An international research team led by Jaime A. Villafaña from the Institute of Palaeontology at the University of Vienna discovered the first fossil nursery area of the great white shark, Carcharodon carcharias in Chile. This discovery provides a better understanding of the evolutionary success of the largest top predator in today's oceans in the past and could contribute to the protection of these endangered animals. The study is published in the journal Scientific Reports.
Scientists from the University of Bristol and the University of Zurich have shown that the Titanichthys – a giant armoured fish that lived in the seas and oceans of the late Devonian period 380-million-years ago – fed in a similar manner to modern day basking sharks.
While smaller dinosaurs needed speed, huge predators like T. rex were optimized for energy-efficient walking, according to a study published May 13, 2020 in the open-access journal PLOS ONE by Alexander Dececchi of Mount Marty College, South Dakota and colleagues.
As bad as things might seem here in 2020, they could be worse: we could be living 252 million years ago during the Permian mass extinction.
Scientists have discovered the world's oldest known example of a squid-like creature attacking its prey, in a fossil dating back almost 200 million years.
100 million years ago, ferocious predators, including flying reptiles and crocodile-like hunters, made the Sahara the most dangerous place on Earth.
Scientists of the University of Vienna examined parts of a vertebral column, which was found in northern Spain in 1996, and assigned it to the extinct shark group Ptychodontidae. In contrast to teeth, shark vertebrae bear biological information, like body size, growth, and age and allowed the team surrounding Patrick L.
The end-Permian mass extinction (EPME), approximately 252 million years ago (Ma), caused a serious marine and terrestrial ecosystem crisis, and about 75% of terrestrial biological species disappeared. How long did it take for terrestrial ecosystems to recover?
Researchers have found evidence of rainforests near the South Pole 90 million years ago, suggesting the climate was exceptionally warm at the time.
A new feathered dinosaur that lived in New Mexico 67 million years ago is one of the last known surviving raptor species, according to a new publication in the journal Scientific Reports.
Three new species of toothed pterosaurs — flying reptiles of the Cretaceous period, some 100 million years ago — have been identified in Africa by an international team of scientists led by Baylor University.
