Our museums remain closed due to COVID-19. While LA County Public Health has entered Phase 3 of the Roadmap to Recovery, allowing for the reopening of museums on June 12, our museums are still slowly welcoming back staff and are in the process of planning for new health and safety protocols in our galleries and gardens. Therefore, we will not be reopening until later in the summer. Sign up here to be the first to know when we will safely re-open to the public and in the meantime, stay connected from home.

Fish Collections

Only three species of fish have been identified from Rancho La Brea thus far. 

Remains of rainbow trout, Oncorhynchus mykiss, (mostly isolated vertebrae) and threespine stickleback, Gasterosteus aculeatus (primarily pelvic spines), are both common. One dentary and two vertebrae represent one individual of arroyo chub, Gila orcutti. This is the first fossil record of Gila orcutti, but both the rainbow trout and particularly the threespine stickleback have extensive fossil records in the Western United States. Collectively the fish fossils indicate local, permanent stream conditions, and not stream transport from distant mountainous areas. No extinct freshwater fishes are known from Rancho La Brea deposits yet.
