The perspective of Jurassic-era Europe as an archipelago is conveyed by “the flooded margins of continents which here and there dive into deep oceanic trenches,” a compelling reminder of the fragile equilibrium between land and water that is relevant to today’s discussion of sea-level rise. The floor is determined by volcanic basalt rock that controls the tectonic plate. Elegant glass sponges reside in the deep sea, and corals collaborate with algae to digest light. The sea’s importance is made explicit by its oneness with the land, and the assertion that oceans and mountains are geologically temporary. Readers meet geese “twice the weight of a mute swan” stocking up for winter and insects colored black and yellow or black and red, “a warning of danger, or poison, or simply unpalatability.” Present are plants so eager to be consumed by insects that they’ll increase sugar production to boost their nectar as “a passing insect’s wings gently vibrates their petals” and bisexual lily-like flowers with “both male and female tissues on one single stem.” The otherworldly flora and fauna abound in proven strangeness. This quality is extended into Halliday’s vivid writing style as he describes giant flightless birds with “can-opener hooks” on the end of their beaks and sediment left behind evaporating water that raises the water source itself “compacted sugar on a growing stack of pancakes.” Art meets Earth science in Halliday’s densely detailed portrayal of our ecosystem’s history, alluding to the “Epic of Gilgamesh,” Gaudi’s architecture and the sepia tones of silent-era films. Merging human culture with the changing environments brings out an accessible human layer that contextualizes the scientific density. By beginning with the most recent period, the Miocene, and progressing backwards until the very earliest, the Ediacaran, Halliday brings deep time’s primordial soup to life. Structured between 16 geologic periods, Halliday’s book takes readers back in time through the millions of years predating our present. Thousands of scientists over hundreds of years have contributed to Halliday’s reconstructions of the past based on the paleontological irony of death being the primary way of understanding life. Thomas Halliday ventures into the vastness of this predicament in his book “Otherlands: Journeys in Earth’s Extinct Ecosystems,” a compendium on Earth’s sprawling origins. If there is one uncertainty that has persisted since the beginning of time, it’s our planet’s impermanence. “Otherlands: Journeys in Earth’s Extinct Ecosystems,” by Thomas Halliday (Random House) This cover image released by Random House shows "Otherlands: A Journey Through Earth's Extinct Worlds" by Thomas Halliday.
