This fossil is quite interesting. It appears to a brachiopod with very long spines. The fossil is from the collection of the late Dr. James Conkin (1924-2017) and had no label with it. The fossil is in a black shale and the only shale found around th...

In April 2024, the AGU Board of Directors gathered in Hoboken, NJ to discuss vital topics shaping the organization's future. The meeting revolved around four key themes: adapting to change, fostering relationships, defining the role of science, and our vision of the future. Framed by a quote from American philosopher Eric Hoffer: "In a world of change, the learners shall inherit the earth, while the learned shall find themselves perfectly ...

I was asked to lead a walk in the old part of Oakland for a group of engineering geologists that ends at a brewpub. The 3.8-mile route I chose feels too good to keep private. It's as much about interesting parts of town as about interesting bits of geology.

I recently had some ventures in the Permian Basin. The Permian Basin looms large in geology lore and American/global policy. The basin extends from southeast New Mexico trough a wide swath of western Texas. The sediments that were deposited in the basin span much of the Cambrian and were capped by a massive carbonate reef building period during the Permian, The long geologic history recorded in the basin rocks and the massive reef building is a subject in many geology text books in a large part because the Permian Basin has garnered a lot of geologic attention - it is the largest oil producing basin in the United States. Hence, the basin subsurface geology has been well explored and there are very good exposures of the basin rocks along the steep slopes of the Guadalupe Mountains on the western edge of the basin where uplift along a steep set of faults provides good cross sectional views of the Capitan Reef.
