The Field Trips
At Red Rock Canyon State Park, California: Visit wildly
colorful Red Rock Canyon State Park on California's northern
Mojave Desert, approximately 130 miles north of Los Angeles--scene
of innumerable Hollywood film productions and commercials over
the years--where the Middle to Late Miocene (13 to 7 million
years old) Dove Spring Formation, along with a classic deposit
of petrified woods, yields one of the great terrestrial, land-deposited
Miocene vertebrate fossil faunas in all the western United States.
Insects And Vertebrates On The Mojave Desert, California:
Journey to two world-famous fossil sites in the middle Miocene
Barstow Formation: one locality yields upwards of 50 species
of fully three-dimensional, silicified freshwater insects, arachnids,
and crustaceans that can be dissolved free and intact from calcareous
concretions; a second Barstow Formation district provides vertebrate
paleontologists with one of the greatest concentrations of Miocene
mammal fossils yet recovered from North America--it's the type
locality for the Bartovian State of the Miocene Epoch, 15.9 to
12.5 million years ago, with which all geologically time-equivalent
rocks in North American are compared.
Visit To Fossil Valley, Great Basin Desert, Nevada:
Take a virtual field trip to a Nevada locality that yields the
most complete, diverse, fossil assemblage of terrestrial Miocene
plants and animals known from North America--and perhaps the
world, as well.
Pennsylvanian Fossils In Kansas: Travel to the midwestern
plains to discover the classic late Pennsylvanian fossil wealth
of Kansas--abundant, supremely well-preserved associations of
such invertebrate animals as brachiopods, bryozoans, corals,
echinoderms, fusulinids, mollusks (gastropods, pelecypods, cephalopods,
scaphopods), and sponges; one of the great places on the planet
to find fossils some 307 to 299 million years old.
From Pleistocene Lake Manix, California: Explore the
badlands of the Manix Lake Beds on California's Mojave Desert,
an Upper Pleistocene deposit that produces abundant fossil remains
from the silts and sands left behind by a great fresh water lake,
roughly 350,000 to 19,000 years old--the Manix Beds yield many
species of fresh water mollusks (gastropods and pelecypods),
skeletal elements from fish (the Tui Mojave Chub and Three-Spine
Stickleback), plus roughly 50 species of mammals and birds, many
of which can also be found in the incredible, world-famous La
Brea Tar Pits of Los Angeles.
Trip To Pleistocene Lake Manix, California: Go on
a virtual field trip to the classic, fossiliferous badlands carved
in the Upper Pleistocene Manix Formation, Mojave Desert, California.
It's a special place that yields beaucoup fossil remains, including
fresh water mollusks, fish (the Mojave Tui Chub), birds and mammals.
Plants Of The Ione Basin, California: Head to Amador
County in the western foothills of California's Sierra Nevada
to explore the fossil leaf-bearing Middle Eocene Ione Formation
of the Ione Basin. This is a completely undescribed fossil flora
from a geologically fascinating district that produces not only
paleobotanically invaluable suites of fossil leaves, but also
world-renowned commercial deposits of silica sand, high-grade
kaolinite clay and the extraordinarily rare Montan Wax-rich lignites
(a type of low grade coal).
In The Marble Mountains, Mojave Desert, California:
Take a trip to the place that first inspired my life-long fascination
and interest in fossils--the classic trilobite quarry in the
Lower Cambrian Latham Shale, in the Marble Mountains of California's
Mojave Desert. It's a special place, now included in the rather
recently established Trilobite Wilderness, where some 21 species
of ancient plants and animals have been found--including trilobites,
an echinoderm, a coelenterate, mollusks, blue-green algae and
Cambrian Fossils Of Westgard Pass, California: Visit
the Westgard Pass area, a world-renowned geologic wonderland
several miles east of Big Pine, California, in the neighboring
White-Inyo Mountains, to examine one of the best places in the
world to find archaeocyathids--an enigmatic invertebrate animal
that went extinct some 510 million years ago, never surviving
past the early Cambrian; also present there in rocks over a half
billion years old are locally common trilobites, plus annelid
and arthropod trails, and early echinoderms.
Visit To The Sharktooth Hill Bone Bed, California:
Travel to the dusty hills near Bakersfield, California, along
the eastern side of the Great Central Valley in the western foothills
of the Sierra Nevada, to explore the world-famous Sharktooth
Hill Bone Bed, a Middle Miocene marine deposit some 16 to 15
million years old that yields over a hundred species of sharks,
rays, bony fishes, and sea mammals from a geologic rock formation
called the Round Mountain Silt Member of the Temblor Formation;
this is the most prolific marine, vertebrate fossil-bearing Middle
Miocene deposit in the world.
Search Of Fossils In The Tin Mountain Limestone, California:
Journey to the Death Valley area of Inyo County, California,
to explore the highly fossiliferous Lower Mississippian Tin Mountain
Limestone; visit three localities that provide easy access to
a roughly 358 million year-old calcium carbate accumulation that
contains well preserved corals, brachiopods, bryozoans, crinoids,
and ostracods--among other major groups of invertebrate animals.
In Millard County, Utah: Take virtual field trips
to two world-famous fossil localities in Millard County, Utah--Wheeler
Amphitheater in the trilobite-bearing middle Cambrian Wheeler
Shale; and Fossil Mountain in the brachiopod-ostracod-gastropod-echinoderm-trilobite
rich lower Ordovician Pogonip Group.
Era Fossils At Mazourka Canyon, Inyo County, California:
Visit a productive Paleozoic Era fossil-bearing area near Independence,
California--along the east side of California's Owens Valley,
with the great Sierra Nevada as a dramatic backdrop--a paleontologically
fascinating place that yields a great assortment of invertebrate
Triassic Ichthyosaur And Invertebrate Fossils In Nevada:
Journey to two classic, world-famous fossil localities in the
Upper Triassic Luning Formation of Nevada--Berlin-Ichthyosaur
State Park and Coral Reef Canyon. At Berlin-Ichthyosaur, observe
in-situ the remains of several gigantic ichthyosaur skeletons
preserved in a fossil quarry; then head out into the hills, outside
the state park, to find plentiful pelecypods, gastropods, brachiopods
and ammonoids. At Coral Reef Canyon, find an amazing abundance
of corals, sponges, brachiopods, echinoids (sea urchins), pelecypods,
gastropods, belemnites and ammonoids.
Visit To Ammonite Canyon, Nevada: Explore one of the
best-exposed, most complete fossiliferous marine late Triassic
through early Jurassic geologic sections in the world--a place
where the important end-time Triassic mass extinction has been
preserved in the paleontological record. Lots of key species
of ammonites, brachiopods, corals, gastropods and pelecypods.
From The Kettleman Hills, California: Visit one of
California's premiere Pliocene-age (approximately 4.5 to 2.0
million years old) fossil localities--the Kettleman Hills, which
lie along the western edge of California's Great Central Valley
northwest of Bakersfield. This is where innumerable sand dollars,
pectens, oysters, gastropods, "bulbous fish growths"
and pelecypods occur in the Etchegoin, San Joaquin and Tulare
Trip To The Kettleman Hills Fossil Field In Kings County, California: Take a virtual field trip to a classic site
on the western side of California's Great Central Valley, roughly
80 miles northwest of Bakersfield, where several Pliocene-age
(roughly 4.5 to 2 million years old) geologic rock formations
yield a wealth of diverse, abundant fossil material--sand dollars,
scallop shells, oysters, gastropods and "bulbous fish growths"
(fossil bony tumors--found nowhere else, save the Kettleman Hills),
among many other paleontological remains.
Bones In The Coso Range, Inyo County, California: Visit the Coso Range Wilderness, west of Death
Valley National Park at the southern end of California's Owens
Valley, where vertebrate fossils some 4.8 to 3.0 million years
old can be observed in the Pliocene-age
Coso Formation: It's a paleontologically significant place that
yields many species of mammals, including the remains of Equus
simplicidens, the Hagerman Horse, named for its spectacular
occurrences at Hagerman Fossil Beds National Monument
in Idaho; Equus simplicidens is
considered the earliest known member of the genus Equus, which
includes the modern horse and all other equids.
Trip To A Vertebrate Fossil Locality In The Coso Range, California: Take a cyber-visit to the famous bone-bearing
Pliocene Coso Formation, Coso Mountains, Inyo County, California;
includes detailed text for the field trip, plus on-site images
and photographs of vertebrate fossils.

Basin Desert of Nevada, a specific place that yields some 41
species of ammonoids, in addition to five species of pelecypods
and four varieties of belemnites from the Middle Triassic Prida
Formation, which is roughly 235 million years old; many paleontologists
consider this specific site the single best Middle Triassic,
late Anisian Stage ammonoid locality in the world. All told,
the Prida Formation yields 68 species of ammonoids spanning the
entire Middle Triassic age, or roughly 241 to 227 million years
Plants And Insects At Bull Run, Nevada:
Head into the deep backcountry of Nevada to collect fossils from
the famous Late Eocene Chicken Creek Formation, which yields,
in addition to abundant fossil fly larvae, a paleobotanically
wonderful association of winged seeds and fascicles (bundles
