Biosignatures of an ancient bedrock- and impact structure-hosted deep biosphere: current knowledge and future perspectives by Jacob Gustafsson, Henrik Drake

“…Abstract The deep biosphere is thought to have dominated life on Earth for most of its history and played a crucial role in the early evolution of both prokaryotes and eukaryotes. Currently, an incoherent record of biosignatures such as body fossils, trace fossils and chemofossils stretching from present to ~ 3.5 Ga implies the presence of an abundant and rich, yet largely unexplored, record of an ancient deep biosphere in fractures, vesicles and vugs of the igneous oceanic and continental crust, and in meteorite impact structures therein. …”

Anatomical and histological analysis of an undescribed cervical skin fold structure in spotted turtles (Clemmys gutatta) by Meghan V. Chung, Mandy Womble, Gregory A. Lewbart, Jeffrey G. Hall, Daniel S. Dombrowski

“…While the function is currently unknown, it is suspected to serve a protective role for the head and neck of the turtle much like the hinged shell of some other chelonians. This structure may provide clues to the evolution between a turtle that has an unhinged shell such as a yellow-bellied slider (Trachemys scripta) and a turtle that has a hinged shell such as an eastern box turtle (Terrapene carolina carolina), utilized for evading predation or danger. …”
