  • Two Roman-era shipwrecks have been found in deep water off a western Greek island, challenging the conventional theory that ancient shipmasters stuck to coastal routes rather than risking the open sea, an official said Tuesday.
  • They lay between 1.2 and 1.4 kilometers (0.7-0.9 miles) deep in the sea between Corfu and Italy.
  • among the deepest known ancient wrecks in the Mediterranean, apart from remains found in 1999 of an older vessel some 3 kilometers (1.8 miles) deep off Cyprus.
  • ...3 more annotations...
  • A Greek oceanographic vessel using side-scan radar and robot submarines took footage of scattered cargo — storage jars, or amphorae, used to carry foodstuffs and wine — cooking utensils for the crew, anchors, ballast stones and what could be remains of the wooden ships.
  • deep wrecks are very important because they are almost always more intact than those found in shallow water
  • far more archaeological and historical information

  • belongs to the Museum of National History in Berlin
  • During World War II, a bomb fell on the museum's east wing, collapsing the basement where dinosaur fossils were stored
  • Making matters worse, bones from two separate expeditions had been housed in the same area
  • ...9 more annotations...
  • One expedition, in Tanzania, ran from 1909 to 1913 and brought back 235 tons of fossils, labeled with letters based on their locations.
  • The other fossils came from a 1909 discovery in Halberstadt, Germany. Those bones also used a letter-based label system
  • individual animals
  • By comparing the scans to sketches of the long-ago digs, the researchers determined that the vertebra came from the Halberstadt dig in Germany
  • The scans showed a fractured bone. Some of the cracks were no doubt from fossilization
  • But one crunched-up corner was likely the result of the bombing
  • To recreate the bone as it was before the bombing, the researchers took data from the CT scan and built a blueprint to 3D print the fossil
  • When the process was done
  • The researchers were even able to print the bone chip from the bombing damage, which fit into the rest of the vertebra like a puzzle piece.
