The Broken Shell Problem

Archaeologists rethink ancient oyster middens and discover that absence can distort the ecological past

Fascinating archaeological discovery at NYC's Conference House! During preparation for roof restoration, materials testing revealed original 17th-century mortar in the attic walls - confirming it dates to the house's construction around 1680. This 350-year-old building material survived centuries while the rest of the structure underwent changes.

Original 17th Century Mortar Found at the c. 1680 Conference House - Historic House Trust of New York City

Mortar found in situ at the historic Conference House on Staten Island was determined through materials testing to be almost 350 years old.  The Historic House Trust of New York […]

"This dyeing tradition came under threat in Oaxaca during the early 1980s when a Japanese company, Imperial Purple Inc., overharvested them. Instead of allowing the mollusks to recover, they collected dye year round. Within four years, the population was severely depleted. Led by anthropologist Marta Turok and the Pinotepa shell dyers, the Mexican authorities were petitioned to protect the purpura habitat. Since 1988, only licensed Mixtec dyers are permitted to harvest dye, taking monthly turns according to the moon cycle, thus creating a healthy environment for the shellfish. The men of Pinotepa de Don Luis continue this practice, trading or selling the dyed cotton to their village women weavers."

The Color Purple-Purpura Shell Dyeing in Oaxaca - ClothRoads

Gone are the days when hundreds of Mixtec men scrambled over the rocky Oaxacan shoreline north of Huatulco to extract the milky liquid from the purpura patula, a marine mollusk. But thankfully to the persistence of a few people, the tradition of shellfish dyeing has survived, for these large mollusks yield the essential rich purple dye, hand woven into the traditional pozahuanco (wrapped skirt) worn by Mixtec women.
