The history of extinct animals

Previously

…The thicktail chub (Gila crassicauda) was a type of minnow that inhabited the lowlands and weedy backwaters of the Sacramento and San Joaquin Rivers in the Central Valley of California. It was once abundant in lowland lakes, marshes, ponds, slow-moving stretches of river,[3] and, during years of heavy run-off, the surface waters of San Francisco Bay.[3] The thicktail chub was one of the most common fish in California.[3] Within Native American middens it represented 40% of the fish.[4]
