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 =>

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.
