Many of the species live today in the Gulf of California and a surprising number survive only in the Caribbean Sea.

More Invertebrates =>
Discoveries from the fossil beds of the Anza-Borrego Desert have contributed to our understanding of the evolutionary history of  many vertebrate lineages.

More Vertebrates =>
The presence of petrified wood scattered across the desert floor tells a vivid story of pre-historic woodlands in the distant past.

More Plants =>
A fossil bird beak found in the 1960s has recently been re-identified as belonging to a “terror bird" - family Phorusrhacidae.

More Terror Bird =>






Forces originating in the relative motion between the Pacific and North American plates are tearing the southwestern edge of  North America apart.

More Geology =>
The climatic and environmental story told by the rocks and fossils of the Park begins about 7 million years ago in the Miocene.

More Paleoclimate =>
Over eighty localities yielding proboscidean remains have been recorded in ABDSP from fragments to a nearly complete skeleton.

More Mammoths =>
3D imagery is being used to record ephemeral sites in the field, such as trackways, and to 3D print copies of unique fossils including the Terror Bird beak.
