Students continued to learn more about stone tools – what they look like, their purpose, and how they were made. In the early stages, starting maybe about 3 million years ago, humans made tools by breaking up stones. The sharp edges flakes were used as knives, whereas others might have been used to crush or [...]
Archaeology, our fifth and final module, started Monday. Students learned a lot about the basics: Archaeology is the study of artifacts and buildings that people have left behind. In Turkana, there are mostly stone tools that range in age from 3 million years to 50,000 years or less. Students learned about stone tools, [...]
Local students went back to visit the Lorengelup primary school where they planted trees a few weeks ago. They had since erected some barriers around these little trees to protect them from the many goats in the area. Associated with the school is a small brand new maternity clinic. To provide power for lights, cooking [...]
Students learned in detail about how decaying organic plant material gets preserved over time (taphonomy). For example, plants can get preserved under volcanic ash, mud slides, or on lake and river bottoms. In all cases, fine sediment or ash completely covers the plant material. To illustrate taphonomy, students went to the river to look at [...]
This week, students will be learning al about the differences among living plants and their adaptations. Did you know that there are many more plants with toothed leaves in colder climates and that most leaves of plants in warm and wet climates have smooth edges? There is a higher rate of photosynthesis in the spiky [...]
The Field School is not all work; there is also some time to relax. On Sunday students went to Eliye Springs on the sandy shores of Lake Turkana. This little “resort” features a small restaurant with fabulous food and cold sodas (special treat!). Students relaxed in the shade under umbrellas and cooled off in the [...]
Students went on a field trip to Kalodir, a site where with exposed sediments that are over 17 million years old. After chipping away sediments students recovered impressions of leaves and other plant parts. Impressions occur when, let’s say a leaf, drifts to the lake bottom where it is covered with fine sediments such as [...]
Time is flying – the forth module kicked off Monday. Students are learning about the evolution of vertebrates (animals with a backbone) and how to identify animal fossils. Students are also learning about the evolution of plants and how to identify plant fossils. Knowing about what types of plants and animals were present at any [...]
This Sunday students went to visit a local school. Of course, Turkana students have off on Sundays too, but many of the 176 children and teachers came to welcome the TBI Field School students. TBI donated around 20 young trees that we all planted together around the school yard. After that, students played some soccer [...]
This week students have been learning about our more recent ancestors that lived over the past 2 million years. At around 1.8 million years there were six or more different species of early human-like species in Africa, and now there is only one left - us, Homo sapiens. Students not only paid close attention to [...]
Yesterday students finally got to look at their fossils in more detail. With the help of instructor Fred Grine and Meave Leakey, students did their best to identify, and piece together, the often very small bone fragments. Finds ranged from mammal bones to crocodile teeth and turtle shells. [...]
On Saturday morning, students went on a short walk to a fossil site just outside TBI. Here, Dr. Meave Leakey taught three different methods of locating fossils. The students had great fun and only reluctantly left for lunch after searching for fossils for over three hours! The ground was littered with fossils, and many, many [...]
Students had a fun and successful day hunting for fossils. The first stop was the site called Losodok - a landscape of rolling hills and - lucky for us - lots of wind. Temperatures can easily sore above 100 F or 40 C during the day. Losodok dates to over 15 million years ago and [...]
Students have been learning more about the animal skeleton and muscles. Bones can tell us about how muscles were attached. Muscles can tell us about what kind of movements an organisms was adapted to performing. So even with only a few key bones, we can learn a lot about an extinct animal. Teeth can reveal [...]
Today students learned the basics about human anatomy and how detailed knowledge of bones is crucial in identifying fossils. Human, or other animal fossils, are very rarely found in one piece – most often found are individual bones, bone or skull fragments, or teeth. Bones can tell us much about an organism: its age, health, [...]
The third module on Human Evolution started early. Professor Fred Grine of Stony Brook University arrived Saturday and took students on an excursion to Lake Turkana. The Turkana Basin has revealed a wealth of human fossils, and is thus also known as "the cradle of human kind". After a short truck ride students arrived [...]
The students went on their first overnight camping trip to Lothagam, a site that dates as far back as eleven million years, and contains fossils and artifacts from as little as several thousand years ago. It consists of a series of faults and outcrops formed by both a once gigantic lake, and volcanic/tectonic activity. [...]
Students really got into the Valentine’s Day spirit, making creative and imaginative gifts and cards for each other! We wish everyone a joyous day filled with love!
Students went on a day trip to Central Island, a volcanic island in the middle of Lake Turkana. After a fun and refreshing 1 hour boat ride students arrived at the island, which consists of several craters filled with water. The first lake visited is named Crocodile Lake which, you guessed it, houses a population [...]
Students learned the concept of superposition, where the oldest sediment or rock layers are on the bottom of an exposed outcrop. However, due to various forces, such as movement of the plates that make up the Earth’s crust, or changes in water bodies, the relative position of rock layers can change. Understanding geology is important [...]
