Walking in the footsteps of giants – and gerbils | Elsa Panciroli

From hopping Cretaceous desert mammals, to muddy Scottish sauropods, fossil footprints reveal more than you might expect about extinct life Trekking through damp woodlands in the Scottish Highlands, I pause and look down at my feet. On a thread-like deer trail on a steep hillside, animal footprints have been pressed into a hollow of mud. Show More Summary

This Poor Cretaceous Damselfly Has Been Waiting 100 Million Years to Get Laid

Scientists in China have discovered male damselflies caught in the act of trying to court females inside a piece of 100-million-year old amber. It’s an extremely rare find, providing a glimpse of insectoid peacocking behavior during the age of dinosaurs. Read more...

Why Did T Rex Have Such Tiny Arms?

2 weeks agoHumor / odd : Neatorama

While Tyrannosaurus rex was the badass of the Cretaceous Period, we get a kick out of poking fun at the dinosaur's tiny forelimbs. We wouldn't do that if it weren't long extinct. Those little "arms" weren't useful for much of anything as far as we know. Show More Summary

Aragonitic scleractinian corals in the Cretaceous calcitic sea

Changes in seawater chemistry have affected the evolution of calcifying marine organisms, including their skeletal polymorph (calcite versus aragonite), which is believed to have been strongly influenced by the Mg/Ca ratio at the time these animals first emerged. Show More Summary

Ancient reptile mystery solved as 2 extinct species found to be the same

(Taylor & Francis Group) Ichthyosaurs, which are similar-shaped to dolphins and sharks, but are reptiles, swam the seas for millions of years during the Triassic, Jurassic and Cretaceous periods. They were the first, large extinct reptiles brought to the attention of the scientific world.

Specialized beetles shed light on predator-prey associations in the cretaceous

(Chinese Academy of Sciences Headquarters) A research team led by researchers from the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences (NIGPAS) found a new morphologically specialized beetle from the mid-Cretaceous Burmese amber, shedding new light on the predator-prey associations in the late Mesozoic terrestrial ecosystem.

Two New Insect Orders?

When a new species of insect is described as being distinct enough to represent a new order, it's kind of a big deal. So it certainly caught my attention over the past year when, not one, but two species from Cretaceous Burmese amber were considered worthy of the honour. Show More Summary

Theory of chaotic orbital variations confirmed by Cretaceous geological evidence

last monthAcademics : Nature

Variations in the Earth’s orbit and spin vector are a primary control on insolation and climate; their recognition in the geological record has revolutionized our understanding of palaeoclimate dynamics, and has catalysed improvements in the accuracy and precision of the geological timescale.

Combining Nd isotopes in monazite and Hf isotopes in zircon to understand complex open-system processes in granitic magmas

Mapping the age and trace element and Sm-Nd isotope compositions of monazite grains from a peraluminous Cretaceous granite using laser ablation–split stream analysis reveals a wide range in Nd isotope and rare earth element (REE) compositions within and between single grains. Show More Summary

Rare Late Cretaceous dino skin found fossilized

About 66 million years ago, a dinosaur lay down on a muddy riverbank in what is now Spain, leaving behind the impression of its scaly skin. A team studying sandstone formations near the village of Vallcebre in the Pyrenees recently uncovered...Show More Summary

Giant winged Transylvanian predators could have eaten dinosaurs | Elsa Panciroli

Welcome to the Cretaceous Romanian island of Ha?eg, once populated by lifeforms stranger than anything imagined by Lovecraft or Geiger What makes ancient, extinct animals so compelling is that they are often beyond anything we can imagine. Show More Summary

A South Dakota education bill has scientists wondering if we’re headed back to the Cretaceous.

Critics worry it would lead schools to ditch lessons about evolution and climate change in favor of teaching ideas like creationism.

Flying Cretaceous Monster Ate Dinosaurs For Breakfast

2 months agoTechnology / Gadgets : Gizmodo

It’s been said that the pterosaur, which can only be described as a bird-reptile-dinosaur-esque-thing, was the largest flying animal. This giant beast—which roamed the Earth during the Cretaceous period roughly 66.5 million years ago—was a reptile but not actually a dinosaur. Despite being winged, it wasn’t bird,… Read more...

How to hide a dinosaur

Analysis of a finely preserved fossil dinosaur from China has revealed the animal’s erstwhile camouflage. It appears that the meter-high Early Cretaceous ceratopsid Psittacosaurus was light-colored on its underside and dark on top, a pattern known as countershading that may hint that the small herbivore lived in a dense forest environment.   11 Jan 2017

A FEATHERED Dinosaur Tail Found Trapped in Amber From Cenomanian Cretaceous Myanmar

A Feathered Dinosaur Tail with Primitive Plumage Trapped in Mid-Cretaceous Amber Authors: Xi et al Abstract: In the two decades since the discovery of feathered dinosaurs, the range of plumage known from non-avialan theropods has expanded significantly, confirming several features predicted by developmentally informed models of feather evolution.
