PERIODIZING GEOLOGICALLY OUTWITH (AND WITHOUT?) THE ANTHROPOCENE: PASTS, AGENCIES, AND THE TERRESTRIAL

History and Theory, EarlyView.
ABSTRACT As a periodization that is generally understood to refer to an era of Terrestrial relationships that developed with modernization and nuclearization, the Anthropocene cannot be applied simply to premodern histories and texts. However, it has introduced historians to geological periodization as a mode of describing periods of changed ...

Is Time Travel Possible? Accidental Signs as Sociolinguistic “Wormholes”

International Journal of Applied Linguistics, EarlyView.
ABSTRACT Sociolinguistics primarily focuses on deliberately staged public signs, while relatively less attention has been given to ephemeral and non‐deliberate signs in urban environments. This study investigates “ accidental signs,” which are hidden historical texts suddenly exposed by unpredictable events.

Subduction Initiation and Early Subduction Zone Development: Insights From the P–T–t Path of the Bay of Islands Metamorphic Sole

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The processes involved during subduction initiation (SI) remain poorly constrained, in part due to the rarity of geological archives. Ophiolites and their underlying metamorphic soles are thought to form during subduction zone infancy and may thus provide critical constraints. Metamorphic soles are derived from oceanic crust of the lower plate

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
