Since the late 1800s, when professional fossil hunters vied with
each other to bring the largest and most complete specimens to the
museum market, Utah has been one of the most fertile grounds for
dinosaur discovery. Because rock from the Mesozoic era covers more
than 25,000 square miles in Utah, the state is a natural museum of
the great age of dinosaurs. The presence of sites such as Dinosaur
National Park and the Cleveland- Lloyd Dinosaur Quarry underline
Utah's ongoing paleontological significance. There are probably
more paleontologists residing and working in Utah now than at any
time in the past, and the state even has an official dinosaur, the
Allosaurus.
Dinosaurs of Utah is an ambitious book bridging the gap between the
voluminous technical literature on Utah's Mesozoic era and the
numerous publications that describe dinosaurs at the elementary
level. "Utah" dinosaurs are presented here as part of the Mesozoic
terrestrial ecosystems that evolved in the Colorado Plateau region
and are discussed in the context of the changing landscapes,
environments, and biota recorded in the geological record.
More than one hundred of author Frank DeCourten's meticulous line
drawings illustrate fossil remains and various features of dinosaur
anatomy, as do five stunning paintings by Carel Brest van Kempen.
More than forty color landscape photographs by John Telford and
Frank DeCourten show modern geologic contexts in most parts of the
state and emphasize the dynamic nature of the region's geologic
history. There is also a series of detailed maps, including several
new to this edition, that show the tremendous topographical shifts
that occurred within the Mesozoic era from the early Triassic to
the late Cretaceous periods, a span of over 175 million years.
This second edition of Dinosaurs of Utah enlivens our understanding
of these amazing vanished creatures by explaining them and their
world to us. It moves beyond the often superficial representations
that have been so prevalent and more accurately portrays the
variety of dinosaurs that once roamed the region now known as Utah.
Many people appreciate the stunning vistas of the Great Basin
desert; understanding the region’s geological past
can provide a deeper way to know and admire this landscape.
In The Great Basin Seafloor, Frank DeCourten immerses readers
in a time when the Basin was covered by a vast ocean in which
volcanoes exploded and sea life flourished. Written for a
nontechnical audience, this book interprets the rock record
left by more than 500 million years of oceanic activity, when
mud and sand accumulated and solidified to produce today’s
Great Basin across parts of modern Utah, Nevada, and
California. DeCourten deciphers clues within exposed slopes
and canyons to reconstruct the vanished seafloor and its
volcanic events and examines fossils to reveal once-thriving
ancient marine communities. Supplemental material is
available online to serve as a field guide for readers
wishing to explore this ancient ocean themselves as they
travel through the region.
