What We Are Reading Today: Deep Time: A Literary History

Author: Noah Heringman 

In this interdisciplinary book, Noah Heringman argues that the concept of “deep time”—most often associated with geological epochs—began as a metaphorical language used by philosophers, poets, and naturalists of the 18th and 19th centuries to explore the origins of life beyond the written record.

Their ideas about “the abyss of time” created a way to think about the prehistoric before it was possible to assign dates to the fossil record.

Heringman, examining stories about the deep past by visionary thinkers ranging from William Blake to Charles Darwin, challenges the conventional wisdom that the idea of deep time came forth fully formed from the modern science of geology.

What We Are Reading Today: ‘Ghost Sharks’

Authors: David A. Ebert, Jenny M. Kemper, Brittany Finucci, Dominique A. Didier, and Marc Dando

Ghost sharks, also known as chimaeras, are cartilaginous fish related to sharks and rays sharing a common ancestor dating back some 400 million years.

These extraordinary fish are found in virtually every ocean on the planet, and while a few inhabit coastal waters, most live at depths that can make them incredibly difficult to study and observe.

This comprehensive reference book covers every known species of chimaera to date.
