Dinosaur Excavations in Wyoming's Morrison Formation

Welcome to Terra Infirma, a Soft Spot on the Hard Rock of Reality! Specimens from these digs are now in London's Natural History Museum and Japan's Fukui Prefectural Dinosaur Museum — plus a live seismograph and weather station in Soquel, California.

Digging Deep Time

Decades of field seasons in Wyoming — the Bighorn Basin and Como Bluff — and years across the West studying its geology and paleontology, from Colorado to Utah. Two dinosaurs came out of the Morrison Formation at Shell, Wyoming: a Stegosaurus excavated in 2004, now at the Natural History Museum in London, and a Camarasaurus excavated in 2007, now at the Fukui Prefectural Dinosaur Museum in Japan. Earlier, at Como Bluff in Medicine Bow, came field seasons with Dr. Robert T. Bakker prospecting the same Late Jurassic beds — all documented in the footage and photographs held in this archive.

Live 24-hour helicorder trace from the Soquel seismic station
Each horizontal line is 60 minutes of ground motion — time runs left to right, top to bottom. Darker traces mean stronger motion. A 24-hour rolling window recorded by a home station in Soquel, California, refreshed here automatically every five minutes. Click the chart for the seismic station — instruments, records and downloads.

Seismology & Data

An EQ-1 seismograph in the basement for distant quakes, and a self-contained geophone indoors that catches anything close to home — two independent instruments in Soquel, California, with over 20 years of continuous seismic monitoring. Helicorder records published daily. The station tracks the San Andreas and Calaveras fault systems and has captured dozens of notable Bay Area and Central California events.

Media & Archives

Field photography, excavation video, helicorder records, and specimen documentation spanning four decades. Includes Como Bluff footage with Dr. Bakker (1994–1995), the Sophie excavation (2004), seismograph records of notable California events, and television coverage of the paleontology fieldwork.

Silver & Stone — The Cyberzoic Silversmith

Handmade sterling-silver jewelry, cut and set at the bench by the same hands that work the quarry — stones chosen the way a geologist chooses them. Every piece is one of a kind; when it is gone there is no second one. No vertebrate fossil material is ever sold.

About Bosco Boscarelli

Robert “Bosco” Boscarelli was born in New London, Connecticut. He grew up in Cleveland, served as a Marine Corps Aviation Electronics Technician working on F-4 Phantoms, built a career of nearly twenty years as an engineer at Xerox, and spent the decades that followed in the field: paleontology, geology, seismology, and wildlife. This archive is the record of that life’s work.
