Manitoba is well-known for its fossil record, including the fossil-filled, world-famous Ordovician-aged Tyndall Stone and the world's largest mosasaurs, or marine reptiles, from the Cretaceous ...

Two nearby explosive massive star deaths, or supernovas, may have triggered mass extinction events in Earth's distant past, new research suggests.

One of the earliest creatures with teeth were conodonts, an eel-like creature that first appeared around 500 million years ago. These creatures also have the record for the sharpest teeth, according ...

The Ordovician saw the transformation of marine benthic communities from the trilobite-based Cambrian Fauna to the brachiopod-dominated Paleozoic Fauna. An evaluation of the changing importance of ...

And—according to a study recently published in the journal Earth and Planetary Science Letters —during an era known as the Ordovician period, it may have once had rings. Seriously.

If you were to look up from Earth some 466 million years ago, you might have seen a gleaming ring stretching across the sky, some scientists say. A study published this month links an uptick in ...

The researchers' idea that Earth once had rings comes from reconstructions of Earth's plate tectonics from the Ordovician period —which ran between 485.4 million years and 443.8 million years ...

A cataclysm engulfed the planet some 252 million years ago, wiping out more than 90% of all life. Known as the Great Dying, the mass extinction that ended the Permian geological period was the ...

UNTIL recently only Devonian conodonts have been known from New Zealand 1, but Ordovician conodonts have now been discovered in the north-western part of the South Island. They seem to be the most ...

Nearly 400 exceptionally well-preserved fossils dating back 470 million years have been discovered in the south of France by two amateur paleontologists. This new fossil site of worldwide importance ...

The conodonts are excellent Paleozoic biostratigraphic tools and the study of the Ordovician conodonts in the Sichuan basin has provided an important basis for the division and correlation of related ...

A period of global cooling around 500 million years ago may have triggered Earth’s largest surge in marine biodiversity. The Great Ordovician Biodiversification Event marked a dramatic explosion ...
