The Cup of Lycurgus
The wonderful chalice you see in the photo has an intriguing characteristic: when illuminated by a direct source, it appears jade-green in colour, while if the light source is placed behind the object, it will appear blood-red in colour. It is a glass chalice, known as 'The Cup of Lycurgus', as it shows a scene involving King Lycurgus of Thrace, an important character in Greek mythology. Purchased in 1950 by the British Museum , the chalice's enigmatic properties have puzzled scientists for decades. A first answer came only in 1990, when a team of English researchers, examining some fragments of the chalice under a microscope,...

Fragment of the granite sarcophagus identified as that of Ramses II
Ramesses II was the third pharaoh of the 19 th Dynasty during the New Kingdom period. His reign is often considered the most celebrated in Egypt's history, marked by several major military campaigns and numerous monument-building projects. Based on supporting historical accounts, most Egyptologists suggest that Ramesses II ascended the throne in 1279 BC and reigned until his death at the age of about 90 in 1212 or 1213 BC. His remains were interred in a tomb complex (designated KV7) in the Valley of the Kings, located opposite the tomb of his sons (KV5) and near the tomb (KV8) of his son and successor, Merenptah. During the reign of ...

The evolution of horny scales in the Permian era

A fossil from the Polish Permian reveals the common origin of horny scales among terrestrial vertebrates, supporting the importance of keratin in animal evolution.

The scales on this lizard playing dead look a lot like those left behind by a reptile and mammal anc
Horny scales, commonly associated with reptiles, have played a crucial role in our evolution, contributing to the formation of fur and feathers. A new fossil discovery provides evidence that scales evolved in the Permian era, before the great divergence of land vertebrates. Scales are essential for maintaining the separation between the inside of an organism and the outside world. In fish, this task is carried out by a layer of scales on the skin, adapted to their aquatic environment. In terrestrial vertebrates, diversity is greater, but a rich fossil record suggests a common origin for scales. The Permian fossil from Bieganów, Poland is ...

800 thousand years ago human footprints from England are the oldest in Europe

The oldest human footprints ever discovered in Europe have been found in England. These are the first human footprints outside Africa. Five people, who lived around 800,000 years ago, imprinted their feet in the mud on the shore of an ancient estuary at Happisburgh, north-east Norfolk.

800 thousand years ago human footprints from England are the oldest in Europe
Perhaps it was a simple British family on some random day 800,000 years ago, but the footprints of up to five people imprinted in the mud of an ancient estuary of Happisburgh, on the coast eastern part of the country are the oldest human footprints ever observed in Europe, the first evidence of human life on the old continent and the first ever found outside of Africa. “At first we didn't know what we were seeing,” explained at the time of the discovery Dr. Nick Ashton of the British Museum. “But as we removed the sand residue, it was clear that the cavities resembled footprints and that we needed to analyze the surface as quickly as ...

We all descend from a single species: a skull that rewrites the man history

A hominid with characteristics previously never observed together in the fossils of one of our ancestor has been found in Georgia. The debate flares up among scholars: did the hominids of 1.8 million years ago all belong to the same species?

We all descend from a single species: a skull that rewrites the man history
The human family tree could be revised, even rewritten, after the discovery of the remains of the hominid from Dmanisi, in Georgia, in which we recognise, as in a "collage", different characteristics never previously observed all together in the fossils of one of our ancestor. As reported in an 2013 article (https://doi.org/10.1126/science.342.6156.297) published in the journal Science, David Lordkipanidze and his colleagues who study the human fossils of Dmanisi, Georgia, dating back to one million and 800,000 years ago, have put forward a proposal that would overturn the entire scheme of our evolution, at least for the l...
