Secret History
The research project into the 1951-1964 excavation archive have shown humans occupied the site in the late 4th or 5th centuries.
Archaeologist John Allan said: "We hadn't realised these periods were represented in the excavated pottery."
Other finds include "exotic" pottery from Italy, Spain, Portugal and France.

Lions and sphinxes line the processional way to the temple at Madinet Madi.
Founded during the reigns of Amenemhat III (about 1859-1813 B.C.) and Amenemhat IV (about 1814-1805 B.C.) of the 12th Dynasty, Madinet Madi contains the ruins of the only Middle Kingdom temple in Egypt.
Approached by a paved processional way lined by lions and sphinxes, the temple was dedicated to the cobra-headed goddess Renenutet, and the crocodile-headed god, Sobek of Scedet, patron god of the region.
Now almost forgotten by tourists, the site was swarming with pilgrims in ancient times.
Indeed, 10 Coptic churches dating from the 5th to 7th centuries and the remains of a Ptolemaic temple dedicated to the crocodile god were unearthed in the past decades by renowned Egyptologist Edda Bresciani of Pisa University, who has been excavating the area since 1978.
To most Costa Ricans - Ticos and expats alike - Costa Rican history begins with the arrival of the Spanish in 1502. Recent developments and archeological finds are painting a far different picture however. In fact, there is increasing evidence that ancient cultures thrived in the land of Pura Vida long before European explorers cast covetous eyes upon its beauty and natural riches.
Three archeological sites in various parts of the country give an interesting glimpse into pre-Columbian life: Guayabo and La Montana complex in Turrialba, the footpaths of Lake Arenal, and . Each site offers a different window into who the ancient Costa Ricans were and how they lived.
Turrialba
The first, and probably the most notable, is Guayabo de Turrialba. This 540 acre - which is roughly 219 hectares - site can be found in Turrialba on the southern slope of the Turrialba Volcano.
The Guayabo National Park monument was established to preserve the ruins of the city even as archeologists continue to unearth details about the settlement and those who lived there. To date, it is estimated that Guayabo was established and inhabited somewhere around 1500 B.C. During the height of its existence, the city may have held between 10,000 and 25,000 people. For unknown reasons, the settlement seems to have been abandoned by 1400 A.D.-nearly a century before the Spanish arrived. Curiously, no record was left by the Spanish as to whether they had discovered the location and, if so, what condition it was in.
The Punjab Archaeology Department will send a team of technical staff, architects and civil engineers within a couple of days to the site for the documentation of the structure for preservation.
Nadia Saquib, the Ferozewala assistant commissioner, told The Express Tribune that she had prohibited all kinds of excavation at the site.
She said the land owners had been directed not to take any step that could harm the historic structure.
While the Punjab Archaeology Department said they were informed about the ruins by a revenue official, Saquib told The Tribune that the ruins were found during a visit by a city government team looking for land to set up a disposal plant.
She said she had informed the Punjab chief secretary, the culture and youth affairs secretary and the archaeology director about the discovery.
"It is now the duty of the departments concerned to preserve the site," she said.
* Henry VIII may have had two rare medical conditions that could explain both his health issues later in life and the miscarriages of two of his wives.
* An X-linked genetic disease might have caused Henry to become paranoid and anxious after his 40th birthday.
* An unusual blood type might have caused the bodies of his wives to attack their fetuses.
Among a long list of personality quirks and historical drama, Henry VIII is known for the development of health problems in mid-life and a series of miscarriages for two of his wives. In a new study, researchers propose that Henry had an X-linked genetic disorder and a rare blood type that could explain many of his problems.
By suggesting biological causes for significant historical events, the study offers new ways to think about the infamous life of the notorious 16th-century British monarch, said Catarina Whitley, a bioarchaeologist who completed the research while at Southern Methodist University.
"What really made us look at Henry was that he had more than one wife that had obstetrical problems and a bad obstetrical history," said Whitley, now with the Museum of New Mexico. "We got to thinking: Could it be him?"
Plenty of historians have written about Henry's health problems. As a young man, he was fit and healthy. But by the time of his death, the King weighed close to 400 pounds. He had leg ulcers, muscle weakness, and, according to some accounts, a significant personality shift in middle age towards more paranoia, anxiety, depression and mental deterioration.
The red paintings, found by chance by archaeologists looking for signs of ancient settlements, were made around the same time as the Altamira Cave paintings -- some of the world's best prehistoric paintings discovered in northern Spain in 1879.
"It was a chance finding," archaeologist Diego Garate told Reuters.
"Although they were difficult to spot because they are badly deteriorated, our experienced eye helped us to identify them."
Experts will further explore the caves for evidence of prehistoric utensils or tools, officials said.
The first homo sapiens arrived in small groups in northern Spain around 35,000 years ago.
They cohabited for a time with the last of the Neanderthals and then developed a significant culture known as the Upper Palaeolithic, producing stone blade tools and decorating cave walls.
Also known as the Mazandaran horse, the discovery was made in a cemetery dating back to the late Bronze and early Iron age, around 3400 BCE, Archaeology Daily reports. "Due to the form, figure and size of the discovered remains of the horse, we now have the oldest evidence for Caspian horse ancestry at hand," said Ali Mahforuzi, director of the team in Gohar Tappeh.
Discovery of the Caspian horse, or the 'Kings' Horse', was made by the team during the eighth season of archaeological research in Gohar Tappeh, a 50-hectare historical site located between the cities of Neka and Behshahr, in the eastern part of the Mazandaran province.

This photo of casts of two palates demonstrates the large size of the teeth of Paranthropus boisei (left), an early human relative that lived in East Africa between 2.3 million and 1.2 million years ago and is known as Nutcracker Man. Much smaller teeth from a human skull are shown on the right. A new study led by University of Utah researchers shows that Nutcracker Man didn’t eat nuts as had been believed for decades, but instead used the large, flat teeth to chew grasses or plants known as sedges.
"It most likely was eating grass, and most definitely was not cracking nuts," says geochemist Thure Cerling, lead author of the study published in the May 2 online edition of the journal Proceedings of the National Academy of Sciences.
Study co-author Kevin Uno, a University of Utah Ph.D. student in geology, adds: "This study provides evidence that Paranthropus boisei was not cracking nuts, but was instead eating mainly tropical grasses or sedges. It was not competing for food with most other primates, who ate fruits, leaves and nuts; but with grazers - zebras' ancestors, suids [ancestors of pigs and warthogs] and hippos."
Archaeologists and volunteers have uncovered what could be the remains of walls dating back to 700 to 500 BC at Nybster in Caithness.
Andy Heald, of AOC Archaeology, said further investigations would need to be made to confirm the structure's age.
"It shows that the coastline during during ancient Roman times was some 3-4 kilometres farther inland than it is now," said Ostia archaeology official Anna Maria Moretti .
The wooden ship was about 11 metres long, making it one of the largest ancient vessels excavated near Ostia Antica, a port city founded some 2,500 years ago and Rome's first colony.
Comment: Unfortunately these researchers never talked about psychopathy, which seems to be what Henry VIII was.
