Struthio kakesiensis is an extinct oospecies of ratite bird known from eggshell fossils found in Laetoli, Tanzania. It was related to the modern day Struthio . [1]
Struthionidae is a family of flightless birds, containing the extant ostriches and their extinct relatives. The two extant species of ostrich are the common ostrich and Somali ostrich, both in the genus Struthio, which also contains several species known from Holocene fossils such as the Asian ostrich. The common ostrich is the more widespread of the two living species, and is the largest living bird species. Other ostriches are also among the largest bird species ever.
Mary Douglas Leakey, FBA was a British paleoanthropologist who discovered the first fossilised Proconsul skull, an extinct ape which is now believed to be ancestral to humans. She also discovered the robust Zinjanthropus skull at Olduvai Gorge in Tanzania, eastern Africa. For much of her career she worked with her husband, Louis Leakey, at Olduvai Gorge, where they uncovered fossils of ancient hominines and the earliest hominins, as well as the stone tools produced by the latter group. Mary Leakey developed a system for classifying the stone tools found at Olduvai. She discovered the Laetoli footprints, and at the Laetoli site she discovered hominin fossils that were more than 3.75 million years old.
Laetoli is a site in Tanzania, dated to the Plio-Pleistocene and famous for its hominin footprints, preserved in volcanic ash. The site of the Laetoli footprints is located 45 km south of Olduvai gorge. The location and tracks were discovered by archaeologist Mary Leakey and her team in 1976, and were excavated by 1978. Based on analysis of the footfall impressions "The Laetoli Footprints" provided convincing evidence for the theory of bipedalism in Pliocene hominins and received significant recognition by scientists and the public. Since 1998, paleontological expeditions have continued under the leadership of Amandus Kwekason of the National Museum of Tanzania and Terry Harrison of New York University, leading to the recovery of more than a dozen new hominin finds, as well as a comprehensive reconstruction of the paleoecology.
Struthio is a genus of birds in the order Struthioniformes, whose members are the ostriches. It is part of the infra-class Palaeognathae, a diverse group of flightless birds also known as ratites that includes the emus, rheas, and kiwis. There are two living species of ostrich, the common ostrich and the Somali ostrich. They are large flightless birds of Africa who lay the largest eggs of any living land animal. With the ability to run at 70 km/h (43.5 mph), they are the fastest birds on land. It is farmed worldwide, particularly for its feathers as they are used as decoration and feather dusters. Its skin is also used for leather products.
Pedetes is a genus of rodent, the springhares, in the family Pedetidae. Members of the genus are distributed across southern and Eastern Africa.
The year 1976 in archaeology involved some significant events.
The Olduvai Gorge Museum is located in the Ngorongoro Conservation Area in Northern Tanzania on the edge of the Olduvai Gorge. The museum was founded by Mary Leakey and is now under the jurisdiction of the Tanzanian government's Department of Cultural Antiquities and is managed by the Ngorongoro Conservation Area Authority. It is a museum dedicated to the appreciation and understanding of the Olduvai Gorge and Laetoli fossil sites.
Ancylotherium is an extinct genus of the family Chalicotheriidae, subfamily Schizotheriinae, endemic to Europe, Asia, and Africa during the Late Miocene-Early Pleistocene, existing for approximately 7.2 million years .
The Asian or Asiatic ostrich, is an extinct species of ostrich that ranged from Morocco, the Middle East to China and Mongolia. Fossils date from the upper Pliocene to the early Holocene. Beads made from shells taken from archaeological sites in India dating to more than 25000 years were found to have traces of DNA and analysis of sequences examined from them show that the species is definitely in the genus Struthio.
Struthio coppensi is an extinct species of ostrich located near Elisabethfeld, Namibia. This Ostrich is believed to have lived during the Miocene, about 20 mya, and is the oldest member of the Struthio genus.
Orientornis is an extinct species of ratite from the Miocene of China.
Dinosaur eggs are the organic vessels in which a dinosaur embryo develops. When the first scientifically documented remains of non-avian dinosaurs were being described in England during the 1820s, it was presumed that dinosaurs had laid eggs because they were reptiles. In 1859, the first scientifically documented dinosaur egg fossils were discovered in France by Jean-Jacques Poech, although they were mistaken for giant bird eggs.
Ileret is a village in Marsabit County, Kenya. It is located in Northern Kenya, on the eastern shore of Lake Turkana, north of Sibiloi National Park and near the Ethiopian border.
LH 4 or Laetoli Hominid 4 is the catalogue number of a fossilized mandible which was discovered by Mary Leakey in 1974 from Laetoli, Tanzania.
Egg fossils are the fossilized remains of eggs laid by ancient animals. As evidence of the physiological processes of an animal, egg fossils are considered a type of trace fossil. Under rare circumstances a fossil egg may preserve the remains of the once-developing embryo inside, in which case it also contains body fossils. A wide variety of different animal groups laid eggs that are now preserved in the fossil record beginning in the Paleozoic. Examples include invertebrates like ammonoids as well as vertebrates like fishes, possible amphibians, and reptiles. The latter group includes the many dinosaur eggs that have been recovered from Mesozoic strata. Since the organism responsible for laying any given egg fossil is frequently unknown, scientists classify eggs using a parallel system of taxonomy separate from but modeled after the Linnaean system. This "parataxonomy" is called veterovata.
Egg paleopathology is the study of evidence for illness, injury, and deformity in fossilized eggs. A variety of pathological conditions afflicting eggs have been documented in the fossil record. Examples include eggshell of abnormal thickness and fossil eggs with multiple layers of eggshell. The identification of egg paleopathologies is complicated by the fact that even healthy eggs can be modified during or after fossilization. Paleontologists can use techniques like cathodoluminescence or thin sectioning to identify true paleopathologies in fossil eggs. Despite the diversity of paleopathologies known from fossil eggs, the vast majority of conditions known to afflict modern eggs have not yet been seen among fossils.
Reptile egg fossils are the fossilized remains of eggs laid by reptiles. The fossil record of reptile eggs goes back at least as far as the Early Permian. However, since the earliest reptile eggs probably had soft shells with little preservation potential, reptilian eggs may go back significantly farther than their fossil record. Many ancient reptile groups are known from egg fossils including crocodilians, dinosaurs, and turtles. Some ancient reptiles are known to have given live birth and are therefore not anticipated to have left behind egg fossils.
Guegoolithus is an oogenus of fossil egg from the early Cretaceous of Spain. It is classified in the oofamily Spheroolithidae, and was probably laid by an ornithopod dinosaur.
Suchoolithus is an oogenus of crocodylomorph eggs from the late Jurassic of Portugal. They are notable for their small size, and for being among the oldest known crocodylomorph eggs.
Serengetilagus is a genus of lagomorph in the family Leporidae. It lived in the Pliocene of Kenya and Tanzania and the Late Miocene of Chad. Serengetilagus is the best-repesented taxon from Laetoli, with approximately 34 percent of fossils in the Laetolil Beds attributed to this genus. Additional specimens from Angola, Morocco and the Ukraine may also belong to this genus. It had a number of specific features unknown in other lagomorphs, such as a "missing" mesoflexid on its third premolar.
