Secret History
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.
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."

The darker cod vertebra, left, was excavated from a shell midden site in Acadia National Park and is estimated to be 2,000 years old. It is shown in comparison to vertebra from a more recently caught cod, right.
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.
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.

Neanderthals 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.
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.
However, they suspect that dozens of other victims may still lie buried there. Poignantly, the nine corpses - mainly of women and children - had been thrown into a two metre deep rock-cut ditch originally built to defend the settlement.
Only ten out of 400 metres of the ditch have so far been excavated. So it's conceivable that the entire rock-cut dry moat could contain literally hundreds of victims. As well as killing the women and children of the ten acre settlement, the attackers also systematically destroyed it, tearing down the dry stone defences with extraordinary ferocity.
"We are holding this exhibition at primary school of Khirsara to mark the World Heritage Day," says superintending archaeologist (excavation branch) of ASI's Vadodara circle Jitendra Nath.
ASI is conducting excavations at Khirsara in Nakhatrana taluka of Kutch district since 2009-10. "The excavations carried during last two seasons have yielded very interesting results," says Nath, adding that the tripartite plan shows that there was a fortified settlement at Khirsara comprising a citadel, a habitation annexed and even a 'ware house'.
Workers of the Arctic Technologies company carrying out geological exploration occasionally found strange circles of stones and then the object was examined by archeologists.
Archeologists were amazed at strange constructions of boulders - these are well distinguishable stone-laid circles six meters in diameter with a crosswise masonry inside.
Quentin Atkinson of the University of Auckland in New Zealand designed a computer program to analyse the diversity of 504 languages. Specifically, the program focused on phonemes - the sounds that make up words, like "c", "a", and "tch" in the word "catch".
Earlier research has shown that the more people speak a language, the higher its phonemic diversity. arge populations tend to draw on a more varied jumble of consonants, vowels and tones than smaller .
Africa turned out to have the greatest phonemic diversity - it is the only place in the world where languages incorporate clicks of the tongue into their vocabularies, for instance - while South America and Oceania have the smallest. Remarkably, this echoes genetic analyses showing that African populations have higher genetic diversity than European, Asian and American populations.

Bone wasting reveals the owner of this skull to have suffered from leprosy. An unhealed gash on the forehead suggests that the man died a violent death, perhaps in battle
Studying ancient leprosy, which is caused by a bacterial infection, may help scientists figure out how the infectious disease evolved.
The find also reveals the warlike ways of the semi-nomadic people who lived in the area between the sixth and eighth centuries, said study researcher Mauro Rubini, an anthropologist at Foggia University in Italy. The war wounds, which showed evidence of surgical intervention, provide a peek into the medical capabilities of medieval inhabitants of Italy.
"They knew well the art of war and also the art of treating war wounds," Rubini told LiveScience.
