Welcome to my site. I am a vertebrate paleontologist specializing in Upper Cretaceous and Paleogene strata and the vertebrate fossils of the San Juan Basin, New Mexico. These preserve a record of the life and history leading up to, and following, one of the most tumultuous times in Earth History; the end-Cretaceous Mass extinction.
Just out! – the latest issue of New Mexico Earth Matters features an article I wrote about New Mexico’s super giant dinosaur Alamosaurus. Click on the image to get to the New Mexico Bureau of Geology Earth Matters website where you can get your free download!
My new book New Mexico Dinosaurs is now available on Amazon!
The number of new dinosaurs from New Mexico has exploded in recent years. New Mexico Dinosaurs is the most up-to-date review of the latest discoveries. It is written 4th+ grade level, so is easy to understand, yet packed with interesting information on the science and history of paleontology, written by an insider – someone with over 30 years of experience in the field of dinosaur science.
ABQ Tom’s Paleontology and Geology Youtube Channel
My channel is on Paleontology and Geology, with a focus on New Mexico. I will showcase the fossils of dinosaurs and other extinct animals and the places where fossils are found, studied, and displayed. Aside from fossils, I will highlight the geology of New Mexico by exploring famous and iconic sites of the state. Join me in my exploration!

I had only recently (1994) been hired as a Curator of Paleontology at the New Mexico Museum of Natural History & Science in Albuquerque…
The Pantodont Pantolambda
Many of the mammals that occur in Paleogene faunas are archaic, meaning they do not have living descendants. For many of these groups, the relationship to extant mammals is not understood. One of the major groups of early Paleocene archaic mammals are the pantodonts. Pantodonts are of special interest because they are geographically widespread; they…
Dinosaurs of the Zuni Basin, New Mexico
One of the most important dinosaur sites in New Mexico that was excavated by teams led by Jim Kirkland and Doug Wolfe, is located in deposits dating to near the end of the Early Cretaceous epoch from the Zuni basin, near the border between New Mexico and Arizona. The Zuni basin contains deposits, called the…
