The paw prints and hoof prints of a few meddlesome animals have been preserved for posterity on ancient Roman tiles recently discovered by archaeologists in England.
"They are beautiful finds, as they represent a snapshot, a single moment in history," said Nick Daffern, a senior project manager with Wardell Armstrong Archaeology. "It is lovely to imagine some irate person chasing a dog or some other animal away from their freshly made tiles."
The artifacts, which could be nearly 2,000 years old, were found in the Blackfriars area of Leicester, the English city where the long-lost bones of King Richard III were discovered under a parking lot in 2012. Wardell Armstrong Archaeology was brought in to dig at a site where a construction company plans to build student housing. [ In Photos: Animal Prints on Ancient Roman Tiles ]
At least one of the tiles is tainted with dog paw prints, and one is marked with the hoof prints of a sheep or a goat that trampled on the clay before it was dry.
"My initial thought was that it must have been very difficult being a Roman tile manufacturer with these animal incursions going on all the time," Philip Briggs, another Wardell Armstrong archaeologist, told Live Science in an email.
The tiles were found in layers of rubble that had been laid down as a hard base for subsequent floors, but the artifacts' original context is unclear, Daffern said.
"We don't know if the tiles were originally part of an earlier building or were bought in from elsewhere specifically to raise and stabilize ground," Daffern told Live Science in an email.
Leicester was the stronghold of an Iron Age group known as the Corieltauvi tribe, and it remained an important city after the Roman conquest of Britain in the first century A.D., as it was located along the Fosse Way, a Roman road that connected southwestern England with the East Midlands.
The excavators say that, in addition to the animal-printed tiles, they've uncovered Roman tweezers, brooches, coins and painted wall plaster. They've also unearthed traces of a large Roman building — perhaps a basilica, with a peristyle, or columned porch — that was largely robbed of its masonry during the medieval era for other construction projects.
The excavation is funded by construction company Watkin Jones. The archaeologists are providing updates on Wardell Armstrong Archaeology's blog.
