Outline for The Anza-Borrego Pleistocene Video
AB desert is a harsh, desert badlands environment
- It holds
secrets to the past and gives them up grudgingly through the fossils
- The A-B
desert is unique for many reasons
offers a continuous record of life from 6 to 0.5 mya (million years
is one of the largest deposits of fossils on the Pacific Slope of
processes have deposited layers of sediments now exposed on the
surface of today's desert floor. It is possible to walk across the
landscape and actually be walking across different periods of time.
fossil record has revealed many spectacular finds only found here.
have unearthed over 550 different types of plants and animals that
existed over the past 6 million years (nobody knows)
have made significant discoveries over the past 150 years from the fossils
found in the desert as well as by the record of the land-rocks, sand,
fault lines, etc.
have been several different epocs of land formation and associated plant
life over the past 6 million years- from a marine (ocean) environment
to a lush river, lake, forest and savannah to today's desert
the Land and the Life It Supported Like From .5 to 1.5 Million Years Ago?-The
- The land
was lush-rivers, lakes, forest and savannah
- What plants
and trees existed? How are they alike or different from today's?
plants-reeds, grasses, etc.
animals existed in the Pleistocene. What was life like for them? Who
were the predators and their prey? What did they eat? What ate them?
How are they like or different from plants and animals today? The video
will handle each group separately and give answers (what we know) about
each as they appear on the landscape.
sloths with boney armor
horses, camels, mammoths and a variety of savannah, river and lake
fact a bird with the largest wingspan ever to fly over North America
(17ft.)-as well as flamingos and other birds
and amphibians that were only found here and no where else in North
The Future Hold?
research reveals new animal and plants-mammoth skulls, etc.
- We are
learning about the great migrations and biotic interchange of animals
across land bridges -- North, Central and South America migrations
research is helping us understand how the desert was formed
