Walter W. Stein
Walter has been exploring for, excavating, preparing, researching and writing about dinosaurs and other vertebrate fossils since 1996. He has a BS degree in Geology from Appalachian State University in Boone, North Carolina. He is the former Curator and co-designer of the Rocky Mountain Dinosaur Resource Center, the former President of the Bighorn Basin Foundation, the former Collections Manager for the Wyoming Dinosaur Center, and Field Collections Manager for Triebold Paleontology. Walter served with distinction on the board of Directors of the Tri-State Museum, then later as Interim-Director of the Museum. He has been a member of the Association of Applied Paleontologic Sciences (AAPS) for over 20 years and is the former Chairman of their online “Journal of Paleontological Sciences”. He has also been a member of the Southwest Florida Fossil Society for over a decade and has recently been named to their board of directors.
Walter has worked on (and/or discovered) well over 30 important dinosaur skeletons including a new species of giant North American Oviraptor (head preparator/excavator) and a potentially new species of Tyrannosaur (discoverer). He has also worked on numerous other vertebrate finds including, the largest mosasaur ever found in Texas, the first ever plesiosaur bone bed from Montana and a very rare, short-necked plesiosaur (one of two of its species) from South Dakota. In between, the big discoveries, Walter has written multiple scientific papers and two books on the study of paleontology; “So You Want to Dig Dinosaurs” (2001) and another called, “The Top 256 Rules of Paleontology” (April, 2009).
Heather O’Neil Stein
Heather O'Neil Stein was born in Michigan in 1970. At the age of 14 she began studying the martial arts which would become a lifelong endeavor and passion. She rapidly earned black belts in three separate styles of karate. In her middle 20's she graduated from a school of natural health and pursued a career as a massage therapist as a deep tissue specialist for 25 years. While working at some of the top spas in the country she provided therapy for celebrities and professional athletes. In the year 2000 she met Walter which reignited her childhood passion for paleontology and anthropology.
Today, after nearly two decades of paleontological preparation experience, she is one of the top paleo-tech preparators in the company using her artistic skills to help restore fragmentary bones.
David Howe
As a child, David wanted to be a Triceratops when he grew up. Forty years later, and after realizing he lacked the required genetic predisposition for growing three horns on his face, he decided to search for dinosaur remains as an alternative. His appreciation of paleontology would lead him to first contacting PaleoAdventures.
When David isn’t in South Dakota with PaleoAdventures, he’s at home in the Chicagoland area managing his family business, T-Rexplorers, LLC, with his wife and 2 children. David’s company is designed to inspire children to find their passion and to encourage children to discover an interest in the natural sciences. T-Rexplorers conducts hands-on dinosaur/paleontology programs for libraries, schools and many other institutions. T-Rexplorers also has a newly finished Dinosaur Lab for fossil preparation.
David enjoys hiking, fishing and spending time with his family and his four dogs. David is an avid drone pilot, having logged 150 hours of flight time. David is also an expert napper.
David shares the passion of ethical paleontological collection and distribution with Walter, Heather and the team of Field Researchers at PaleoAdventures.
Dan Albro
Dan Albro is a wildlife biologist, and U.S. Air Force Veteran studying and enjoying the planet in all her glorious forms. He enjoys teaching people from all over the world about the human caused dangers facing our world through multiple not-for profits and educational groups. Dan's fascination with fossils started when he lived in Maryland, combing beaches and finding Miocene period shark teeth. Dan moved to California in 2005 to work at the Monterey Bay Aquarium where he helped train docents, led tours and participated in underwater dive programs for over 12 years. When not at the aquarium he collected fossils at the world famous “Shark Tooth Hill” dig sites in Bakersfield, California. Dan is an avid diver and often travels to Florida to scuba dive for Megalodon teeth. Dan's fossil hunting expeditions peaked when he found PaleoAdventures in 2013. After a few years as a volunteer, Dan joined the PaleoAdventures team as a summer guide in 2017. He has found more dinosaur fossils in the Tooth Draw deposit than any other person, except for Walter. Dan is currently on assignment saving the planet.
Becca Ortiz
Becca is the current owner of our main ranch and has grown up with dinosaurs her whole life. She was raised at Deers Ears ranch and grew up looking for fossils with her mom Mary Ann, her dad Leonard and her brother Mike. Her mother, Mary Ann, found the tooth draw quarry in the early 1980’s and inspired the family to explore, dig and collect. From then on Becca began to learn all she could on fossil identification and preservation. As her knowledge grew she shared that information with others and the family began to enjoy hunting for fossils together. Becca has continued to learn from many others who have a love for dinosaurs and fossil hunting. She enjoys sharing her memories of the ranch and fossil collecting with others from all over the world who come to enjoy the Tooth Draw Quarry.
Becca and her husband Tony run the cattle ranch now, along with many other entrepreneurial businesses in the Black Hills.
