MY LEARNING REPORT ABOUT THE TRIP TO THE CRADLE OF HUMANKIND IN STERKFONTEIN
The mammal like reptile from Karoo called Lystrosaurus was known 245 millions years ago and it was a vegetarian. The Thrinaxodon, ancestor of mammals ate all small animals and it was 2m long slender build. The South African dinosaurs called Massospondylus lived 200 millions years ago. The foot of the Australopithecus from Sterkfontein was 3.3 millions years ago had human like features and it was found to be the direct common ancestor of Homo (H. habilis). Mrs Ples (Australopithecus Africanus) from Sterkfontein was known 2.6 millions years ago. He (Mr Mokwena) said that the starlight which is seen from the Andromeda nebula had taken 2.6 millions years to reach planet earth and it is 2.6 millions years light year away from our planet. At the cave there is the elephant chamber or African map, named because the dolomite rock looked like an elephant or an African map. We managed to see the ground water and the water is clear. We also saw some of the fossilized rock and he told us that there is a complete skeleton but we are not allowed to see the skeleton. At the museum we saw the hominids, the teeth, the skull, etc.
There was also the techniques of dating used by the researchers are as follows: They (Cradle of Humankind) used Palaeomagnetism method for dating deposits, Uranium Series dating was used to date infill and stalagmites, and Cosmogenic Isotope dating was used to obtain the date of about 4.1 millions years far the Littlefoo skeleton. Comparison method used to estimates the age of the hominids obtained by comparing them. Cutting edge of Science is a species age of different members of Sterkfontein difficult to determine, as methods of dating and knowledge of contextual evidence or constantly being refined and updated. And the Age of Sterkfontein deposits, there are six members of rock; containing fossils dating between 4 millions to 1.5 millions years ago that gives us an extraordinary timeline of fauna and flora development during the time of our hominid ancestor.
