Coarse, clear halite from synsedimentary dissolution pipes in the Permian Salado Formation in southeastern New Mexico (USA) yielded viable halotolerant bacteria and well-preserved cellulose believed to be Permian in age. Here, we show that geologic a

In this study, we utilized transmission electron microscopy to examine the contents of fluid inclusions in halite (NaCl) and solid halite crystals collected 650 m below the surface from the Late Permian Salado Formation in southeastern New Mexico (US

Willerslev and Hebsgaard's comment on the evidence for the 250 Ma age of the halite, brine inclusion, and Virgibacillus strain 2-9-3 reported in [Satterfield et al. (2005)][1] comes at a time when earth scientists are busily searching for signs of mi

Hazen and Roedder touch on several geological issues raised by our limited description of the Permian Salado Formation. In our study, we sampled coarse halite in dissolution pipes for testing for viable Permian-age bacteria.

The purported oldest living organism, the spore-forming bacterium Virgibacillus sp. Perm- ian strain 2-9-3, was recently cultured from a brine inclusion in halite of the 250 Ma Permian Salado Formation. However, the antiquity of Virgibacillus sp. 2-9

Mining operations in the Permian Salado Formation for the Waste Isolation Pilot Plant (WIPP) reveal filled pits in halite beds which are interpreted as synsedimentary dissolution features. The pits range from a few centimeters to as much as 1 m wide
