fossiliferous deposits at the site of Sterkfontein -- the
richest pre-human fossil site in southern Africa!

The first fossils
at Sterkfontein came to light as early as 1936 and were the first
adult Australopithecines or more specifically Australopithecus.
Australopithecus africanus existed only in South Africa between
3.2 to 2.6 million years ago and was a very early hominid (i.e.
a species that belongs in our family the Hominidae). It was the
adult ape-men fossils from Sterkfontein that helped prove to the
world that Africa was the cradle of humankind. Sterkfontein has
fossil deposits dating back to almost 3.5 million years ago all
the way up to 1.5 million years ago, providing a wealth of information
about the different hominid species that existed in this 2 million
year interval.

I have provided
below a snapshot of some of the firsts yielded by Sterkfontein as
well as some of Sterkfontein's major contributions to the study
of our early human ancestry below:
·The
1st adult Australopithecine, Australopithecus africanus, that the
world had ever seen, discovered in 1936.
· The
most complete skull of Australopithecus africanus, or commonly and
affectionately known as Mrs. Ples found in 1947.
· The
1st partial skeleton of any early hominid ever found, known only
as Sts 14. It was found in 1947 and demonstrated without a doubt
convincing proof that these early hominids walked upright, or bipedally.
· The
first find of a fossil of our genus, Homo, or more specifically
Homo habilis found in 1976. · Geologically earliest record of any
hominid (human ancestor) in South Africa at close to 3.5 million
years ago.
· Fossils
of 500 fossil specimens of one species, including both adults and
children. This is a remarkable sample enabling scientists a look
at a population of hominids instead of just a single fossil. It
has allowed scientists to make inferences about the past demography,
the variability of growth and development, the differences between
the sexes and a whole host of other insights into this population
group known from only 3 sites in the world and only from South Africa.
Sterkfontein
has been intermittently excavated from 1936 to 1965, but in 1966
Professor Tobias of the University of the Witwatersrand initiated
full-time excavations which for the last 34 years from 1966 to the
present have been conducted none stop 5 days a week. This is more
than 62 years in total, but it is amazingly still yielding up its
secrets. The discovery just recently of the almost complete skeleton
of 'Little Foot', which made headlines around the world, bears ample
testament to the wealth of information which is still to be gained
from the cave deposits at Sterkfontein.

SWARTKRANS

|
Palaeo-Tours
offers the unique opportunity for you to visit the actual fossiliferous
deposits at the site of Swartkrans --the second richest pre-human
fossil site in southern Africa!

Fossil hominids
were found at the Swartkrans cave site as early as 1948, but it
seems it has unrightfully, at least in the public domain, taken
a backseat to the finds from Sterkfontein. Swartkrans is in its
own right, an amazing fossil site dating between 2 to 1 million
years ago that has provided its own wealth of information about
this period of human evolution. It is worth noting here that each
fossil site samples different times and different environments and
each provides a piece of the puzzle in our ever-clearer understanding
of human evolution.
Swartkrans was
dug intermittently between 1948 to 1964, but starting in 1965 full-time
excavations were started by Dr. C.K. Brain of the then Transvaal
Museum, Pretoria (now known as the NorthernFlagship Institute -
Pretoria) which lasted for 21 years until 1986. It has now been
left fallow, preserving for future generations a witness section
which scientist in the future will be able to excavate.

It is definitely
worth noting and listing some of the remarkable finds at Swartkrans,
which has provided scientists with a remarkable look into the cultural
lifeways of these early hominids. However, before I list some of
Swartkrans' firsts, which can be found below, I would like to emphasize
its contribution to our study of human evolution.
Swartkrans has
provided the largest sample (more than 126 minimum number of individuals)
of a different type of fossil hominid known as Australopithecus
robustus. This is a very different type of hominid than that found
at Sterkfontein, but also only found in South Africa which went
extinct around 1 million years ago. Also, Swartkrans has provided
the first evidence for the co-existence or species living at the
same time of two different types of hominds, Homo erectus and Australopithecus
robustus. This was the first indication to the scientific community
that hominid evolution did not proceed in a linear fashion from
one species to the next to the eventual end at us, Homo sapiens.
Instead, it demonstrated that human evolution proceeded in a more
bushy arrangement with a number of different species adapting to
different environments at different times. In other words, there
were a number of different experiments in human evolution, some
which succeeded and some that failed and subsequently became extinct.
·
The largest sample of Australopithecus robustus in the
world.
·
The first evidence of 2 species of different types of hominids,
Homo erectus and Australopithecus robustus, living at the same time.
·
The first and earliest evidence for the controlled use of fire found
anywhere at approximately 1 million years ago. It is believed that
the hominid which was responsible for this had the cognitive ability
to take a burning log back from a naturally caused fire, a veldt
fire (a grassland fire), back to the cave, but that it did not have
the cognitive ability to make one itself. This is still this is
an amazing leap forward for our human ancestors.
·
The evidence that hominids used bone tools, which were probably
used for digging roots and tubers.
·
A wealth of stone tools.

DRIMOLEN
|
|
Palaeo-Tours
offers the unique opportunity for you to visit the actual
fossiliferous deposits at the site of Drimolen -- the pre-human
fossil site first to yield a virtually complete skull of Australopithecus!
|
 |
This site
was only discovered in 1992 and is already the third richest
hominid site in southern Africa. On the 26th of April 2000,
the most complete female Australopithecus robustus skull (nicknamed
Eurydice) along with a complete male jaw (nicknamed Orpheus)
made world headlines, see picture below. The site has already
unearthed 79 hominid fossils, a wealth of faunal remains and
some remarkably well-preserved juvenile hominids. As the site
is being excavated year round, visitors to Drimolen are afforded
the unique opportunity to be among the first individuals to
see fossils dating back to 2 million years coming to light!

fossil site of Drimolen provides an excellent opportunity
to see an excavation in progress

Drimolen's
Eurydice & Orpheus
|
|
The
skull (far right) is the most complete skull of its kind
ever found. It was nicknamed by it discoverer Eurydice after
the Greek legend because it was found lying almost cheek
to jowl next to a male mandible (far right)nicknamed Orpheus.
Both
specimens date between 2 to 1.5 million years ago. This
species, Australopithecus robustus, lived successfully for
nearly a million years and lived along side species within
our own genus, Homo.
