Part of an old sailing ship, probably dating from the 18th century, was washed ashore on Tuesday at Ponte Vedra Beach, Florida.
Early Wednesday morning, Julie Turner and her eight-year-old son hit the ship, CBS47 reported. The first two thought it was part of the fence, but shortly thereafter it became "a historic piece of artifact," Turner told the news channel. It was later designated as a well-preserved part of a wooden ship hull.  "To actually see that, survive and come ashore, this is very, very rare, this is the holy grail of shipwrecks," said Marc Anthony, owner of the Spanish Major Antiques in St. Augustine, CBS47.
Anthony, who searched for shipwreck artifacts and treasure coins for more than 20 years, said the wreck seemed eighteenth-century.
According to the St. Johns County Sheriff's Office, officials for Guana River State Park at Ponte Vedra demanded that archaeologists further investigate the wreckage.
Researchers with the St. The Augustine Lighthouse and the Maritime Museum have documented the artifact and say it could date back to the 18th century.
They "take a lot of notes, make drawings, draw them out, there are so many details to try." judge the date where it came from, "said Tonya Creamer, who works in the museum, versus CBS47.
Researchers also took pictures and measured the ship to make a 3D model of it.
What? The next age is not clear.
Creamer said that because the ship was washed ashore ashore, Florida officials eventually decided what to do with the artifact, but there is a possibility that the 48-foot section of the ship could be recovered by the sea.
Creamer was not immediately available for additional comment when Fox News contacted on Thursday.
