@WFS,World Fossil Society,Athira,Riffin T Sajeev,Russel T Sajeev. A group of scientists has found a fossilised lower jaw of a giant creature that one roamed the Earth. Named Tartarocyon cazanavei, it lived in what is now France – between 12.8 and 12 million years ago. Also known as the bear-dog, the fossilised body part of the […]

Prehistoric peopling in southeast Asia: Genomics of Jomon and other ancient skeletons
Uncovering the expansion processes of human habitats in the past is of great importance for understanding the origins and establishment of present-day populations and the acquisition of genetic characteristics of individuals as well as for investigating mechanisms of resistance against diseases and pathogens. Previous genetic/genomic studies aimed to uncover the expansion processes using present-day human […]
Earth’s ancient biosphere deciphered using prehistoric lake deposits.
A sample of ancient oxygen, teased out of a 1.4-billion-year-old evaporative lake deposit in Ontario, provides fresh evidence of what the Earth’s atmosphere and biosphere were like during the interval leading up to the emergence of animal life.
How to Read a Prehistoric Temperature
Here’s a recipe for a mass extinction: Introduce a sudden ice age that piles the land with ice, and then, a few hundred thousand years later, rapidly warm the world. This one-two punch killed off about 50% of Earth’s genera 445 million years ago, ranking it as the third largest mass extinction, right below the […]
Prehistoric crocodilian diversity depends on sea temperature
The ancestors of today’s crocodiles colonised the seas during warm phases and became extinct during cold phases, according to a new Anglo-French study which establishes a link between marine crocodilian diversity and the evolution of sea temperature over a period of more than 140 million years. The research, led by Dr Jeremy Martin from the […]
