Alf's paleontology career unofficially began in 1935, when he spotted a fossil horse jaw at a photo shop and learned that it was found near Barstow.

Alf and Bill Webb took the specimen to Chester Stock, a paleontologist from the California Institute of Technology, who identified it as a new species of Miocene-age peccary.

[5] Inspired by the discovery of "Dyseohys fricki", Alf began the long-standing museum tradition of leading summer and weekend paleontology expeditions (known as Peccary Trips) for Webb students to fossil-rich areas in the western United States.

When he returned to Webb to teach, Alf added paleontology into his biology curriculum and established a small museum in the basement of the school's library.

Dinosaurs are represented by casts of skulls (Diabloceratops, Gryposaurus, Nanotyrannus, Pachycephalosaurus, Tyrannosaurus rex), and skeletons of Allosaurus and Centrosaurus, among others.

A large collection of fossil mammals from North America, including saber toothed cats, brontotheres, and three-toed horses is also featured.

The exhibit ends with a series of temporary displays which show the results of recently completed research projects of museum staff and Webb students.

Currently on temporary display is “Baby Joe”, a young Parasaurolophus discovered in 2009 by students in the Kaiparowits Formation in southern Utah.

The Raymond Alf Museum of Paleontology acts as a unique resource for students of The Webb Schools as they have the opportunity to function as actual paleontologists through hands-on field, lab, and class-based activities.

As part of the freshman science curriculum, every Webb student learns the basics of the geological time, evolution, and other processes that shape our planet.

Study of the museum’s collections or loan of specimens may be arranged by contacting the Augustyn Family Curator of Paleontology, Dr. Andrew Farke.

Special hands-on learning activities are offered to the public on Family Science Discovery Days, which occur on the second Saturday of each month.

The museum also hosts an annual "Fossil Fest", an event that celebrates the excitement of paleontology through hands-on learning for visitors of all ages.
