Known today for its bloody conflicts and instability, Somalia's little known history can be found in the colorful cave paintings of animals and humans discovered in 2002 by a French archaeology team.

Laas Gaal, Somalia (also known as Laas Geel), just outside of Haregeisa, the capital of Somalia's self-declared Somaliland state, contains 10 caves that show vivid depictions of a pastoralist history which dates back to some 5,000 years or more, reports AFP.

A French archaeology team was sent in 2002 to survey Somalia in search of rock shelters and caves that might contain stratified archaeological infills that could document the period when production economy appeared in this part of the Horn of Africa, according to Wikipedia.

During the survey, the Laas Geel cave paintings were discovered. The paintings were in excellent condition, depicting ancient humans who lived in the area raising their hands and worshipping humpless cows with large lyre-shaped horns.

Although the paintings were known to the local Somali people for centuries, it was not advertised to the international community until a team of experts returned to the area in November 2003 to study the paintings and their prehistoric context in detail.

Even with the history of Somalia wars, natural weathering, animals and other factors, the paintings have been well preserved and have retained their clear outlines and vibrant colors.

Accounts by his inner circle give new insight into dictator's life.

It's one of the great questions of history, and indeed philosophy: what does it take to create a Hitler or a Stalin? What circumstances does it require to produce such evil? Newly released diaries from one of Joseph Stalin's personal doctors suggest that, in Stalin's case, illness could have helped to contribute to the paranoia and ruthlessness of his rule over the Soviet Union.

Alexander Myasnikov was one of the doctors called to Stalin's deathbed when the dictator fell ill in 1953, and, in diaries that have been kept secret up to now, he claims that Stalin suffered from a brain illness that could have impaired his decision-making.

"The major atherosclerosis in the brain, which we found at the autopsy, should raise the question of how much this illness - which had clearly been developing over a number of years - affected Stalin's health, his character and his actions," Dr Myasnikov wrote in his diaries, excerpts of which were published for the first time in the Russian newspaper Moskovsky Komsomolets yesterday. "Stalin may have lost his sense of good and bad, healthy and dangerous, permissible and impermissible, friend and enemy. Character traits can become exaggerated, so that a suspicious person becomes paranoid," the doctor wrote.

A scientific battle over the fate of Easter Island's natives is ready to erupt this summer with the publication of a book challenging the notion that their Neolithic society committed ecological suicide.

The debate has a modern political dimension. At stake is the central example, cited by Jared Diamond in his 2005 book Collapse: How Societies Choose to Fail or Survive, of the dire consequences that threaten if humans don't take care of the planet.

The archaeological argument revolves around the moai, hundreds of stone statues that line the coast of the now treeless South Pacific island, known to its inhabitants as Rapa Nui.

The almost-naked natives discovered by a Dutch expedition on Easter Sunday 1722 were considered too impoverished to have carved and moved the statues themselves.

The accepted theory is that a more advanced civilisation, numbering some 15,000 people, must have erected the statues, with hundreds of men hauling them to the shore and whole industries devoted to making ropes, rollers and sledges while the rest struggled to feed the workers.

Just before Easter 1900, Greek sponge-fishers were on their way to the waters of Tunisia when a violent storm threw their boats to Antikythera, a tiny island located north of Crete in the Aegean.

After the storm, the sponge-fishers explored the waters of Antikythera for sponges. One of the divers, Elias Stadiatis, discovered the remnants of an ancient ship full of statues - horses, men, women and vases.

Of several treasures, the most precious was a very small piece of metal with gears, which the archaeologists of the National Museum in Athens originally dubbed astrolabe, which in Greek means, "star catcher." Astrolabes helped figure out the position of the sun and the stars in the sky. Astrolabes were not complicated devices. However, the machine of Antikythera was complex and, eventually, Greek archaeologists renamed it the Antikythera Mechanism and dated it from 150 to 100 BCE.

The shipwreck probably happened in the middle of the first century BCE. The doomed Roman ship was sailing from Rhodes to Rome. It carried looted Greek treasure: more than 100 bronze and marble statues, amphorae and coins.

Authorities say 'Andreas K.' found jewels and ornaments in his backyard

A man turning dirt in his backyard stumbled onto buried treasure - hundreds of pieces of centuries-old jewelry and other precious objects that Austrian authorities described Friday as a fairy-tale find.

Austria's department in charge of national antiquities said the trove consists of more than 200 rings, brooches, ornate belt buckles, gold-plated silver plates and other pieces or fragments, many encrusted with pearls, fossilized coral and other ornaments. It said the objects are about 650 years old and are being evaluated for their provenance and worth.

While not assigning a monetary value to the buried bling, the enthusiastic language from the normally staid Federal Office for Memorials reflected the significance it attached to the discovery.

"Fairy tales still exist!" said its statement. "Private individual finds sensational treasure in garden."

It described the ornaments as "one of the qualitatively most significant discoveries of medieval treasure in Austria."

Sri Lanka's National Archaeological Department has discovered the parts of 20 ancient vessels in the south of the country, an archaeologist said Thursday.

Sanath Karunarathne, an archaeologist with the National Archaeological Department said the ancient vessel parts were discovered as they were conducting a marine archaeological survey in the southern coastal belt.

Karunaratne said they have also been able to locate wreckage of a very ancient ship close to the historical Godavaya Port in the Hambantota District.

An archaeological research team in Northumberland has unearthed a medieval hall underneath Bamburgh Castle.

Bamburgh Castle Research Project dug up a small trench under the inner courtyard at the core of the castle and discovered an Anglo-Saxon hall.

The team believes that the discovery probably dates back to medieval times.

The dig was carried out after the researchers invited Channel 4's Time Team to the castle to help them with their latest archaeological project.

Graham Young, Director of Bamburgh Castle Research Project, said: "Although it's a small trench, because we've seen rock-cut structural features elsewhere, we can fit that into a background.

"We know it's occupied, it's written about in contemporary texts so it's fascinating to see the actual material itself, the archaeology."

An archaeological research project focusing on the food remnants left by pre-Columbian inhabitants of coastal Maine is shedding new light on the diet and habits of some of Maine's earliest citizens. The big find: indigenous people in Maine held to the coast during the winter until the arrival of Europeans changed their long established migratory patterns.

A team of researchers led by Dr. Arthur Spiess - who is both the lead archaeologist for the Maine Historic Preservation Commission and a board member with Abbe Museum in Bar Harbor - have since the summer of 2010 been examining items recovered from a coastal shell midden within Acadia National Park. The project was funded by the L.L. Bean Acadia Research Fellowship and was facilitated by Acadia National Park staff.

A shell midden is essentially an ancient dump site where the leftovers of the meals of native Maine inhabitants were discarded. According to Spiess, the discovery of clam and mussel shells mixed with bones of other food animals at such sites is a great boon to archaeologists. Typically, the acidic soil common to Maine will cause most discarded bones to completely decompose within 100 years. The presence of shells at midden sites has the effect of neutralizing the soil, allowing fish, bird and mammal bones to remain intact for millennia. There reportedly exist thousands of shell middens worth excavating along the coast of Maine, three quarters of which are located around Frenchman Bay.

The items Spiess and his team have been studying recently are estimated to be around 2,500 years old - a period of time known as the ceramic period - and were excavated from a site within Acadia National Park in the late 1970s by University of Maine archaeologist Dr. David Sanger. For Spiess, the research of items from the Acadia shell midden site is one small part of a larger study.

Historical secrets uncovered during one of Wales' largest community archaeology projects are to be revealed at a public meeting.

Local volunteers joined archaeologists to investigate several ancient sites in Cwmbran, Torfaen, with obscure origins.

The research focused on sites of archaeological interest in the Thornhill and Greenmeadow areas, one of which dates back more than 3,500 years.

Project leader Richard Davies said the work had "only scratched the surface".

Cwmbran is mainly known for the post-war new town, but the area has been inhabited since Neolithic times.

The Iron Age Silures tribe later held sway before being subdued by the Romans but this 18-month series of investigations has proved a history stretching back to the Bronze and Stone Ages.

Evidence for a likely 50,000-year-old Neanderthal burial ground that includes the remains of at least three individuals has been unearthed in Spain, according to a Quaternary International paper.

The deceased appear to have been intentionally buried, with each Neanderthal's arms folded such that the hands were close to the head. Remains of other Neanderthals have been found in this position, suggesting that it held meaning.

Neanderthals therefore may have conducted burials and possessed symbolic thought before modern humans had these abilities. The site, Sima de las Palomas in Murcia, Southeast Spain, may also be the first known Neanderthal burial ground of Mediterranean Europe.

"We cannot say much (about the skeletons) except that we surmise the site was regarded as somehow relevant in regard to the remains of deceased Neanderthals," lead author Michael Walker told Discovery News. "Their tools and food remains, not to mention signs of fires having been lit, which we have excavated indicate they visited the site more than once."

Walker, a professor in the Department of Zoology and Physical Anthropology at the University of Murcia, and his colleagues have been working at the site for some time. So far they have found buried articulated skeletons for a young adult female, a juvenile or child, and an adult -- possibly male -- Neanderthal.
