The Ancient footprints of Acahualinca (Spanish pronunciation: [akawaˈliŋka] ; Spanish : Huellas de Acahualinca) exist in Managua, Nicaragua near the southern shore of Lake Managua. The region was once called "El Cauce". The tracks are fossil Late Holocene human footprints left behind in volcanic ash and mud, which solidified about 2,120±120 years ago, shortly after the group of up to 15 people passed by.
Spanish or Castilian, is a Western Romance language that originated in the Castile region of Spain and today has hundreds of millions of native speakers in the Americas and Spain. It is a global language and the world's second-most spoken native language, after Mandarin Chinese.
Managua is the capital and largest city of Nicaragua, and the center of an eponymous department. Located on the southwestern shore of Lake Managua, it had an estimated population 1,042,641 in 2016 within the city's administrative limits and a population of 1,401,687 in the metropolitan area, which additionally includes the municipalities of Ciudad Sandino, El Crucero, Nindirí, Ticuantepe and Tipitapa.
Nicaragua, officially the Republic of Nicaragua, is the largest country in the Central American isthmus, bordered by Honduras to the northwest, the Caribbean to the east, Costa Rica to the south, and the Pacific Ocean to the southwest. Managua is the country's capital and largest city and is also the third-largest city in Central America, behind Tegucigalpa and Guatemala City. The multi-ethnic population of six million includes people of indigenous, European, African, and Asian heritage. The main language is Spanish. Indigenous tribes on the Mosquito Coast speak their own languages and English.
It is sometimes reported that the people were running to escape from a volcanic explosion, but the distance between the footprints indicates a walking gait.Fossilized footprints of several animals are also present, but the fact that they intersect the human footprints shows they were not traveling with the people.
In 1874, construction workers discovered the footprints. The United States medical doctor and archaeological collector, Earl Flint, brought the footprints to the attention of the international science community and media in 1884.
The Carnegie Institution of Washington began the first scientific analysis and excavations of the area in 1941 and 1942. They also constructed a museum and a building to protect the footprints.
Work was continued by Joaquín Matilló, Allan L. Bryan and Jorge Espinosa in the 1960s and 1970s. Allan L. Bryan, from the University of Alberta, used radiocarbon dating to determine the age of soil humates, from a buried soil directly underlying the footprints, to 5,945±145 radiocarbon years Before Present.Based upon this date, he estimated that the footprints dated to about 5,000 Before Present. But, later dating of the volcanic deposits in which they occur, known as the Masaya Triple Layer, demonstrated that the fossil tracks are only about 2,120 ± 120 years old. In 1978, the Nicaraguan researcher Jorge Espinosa continued the excavation near the termination of the original excavation. He uncovered more footprints at a depth of 4 meters. The track is believed to continue further.
The University of Alberta is a public research university located in Edmonton, Alberta, Canada. It was founded in 1908 by Alexander Cameron Rutherford, the first premier of Alberta, and Henry Marshall Tory, its first president. Its enabling legislation is the Post-secondary Learning Act.
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
Before Present (BP) years is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred in the past. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date of the age scale, reflecting the origin of practical radiocarbon dating in the 1950s. The abbreviation "BP" has alternatively been interpreted as "Before Physics"; that is, before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, making dating after that time likely to be unreliable.
Specimens of these footprints can be viewed at both the Peabody Museum of Archaeology at Harvard University and the United States National Museum.
The Peabody Museum of Archaeology and Ethnology is a museum affiliated with Harvard University in Cambridge, Massachusetts. Founded in 1866, the Peabody Museum is one of the oldest and largest museums focusing on anthropological material, with particular focus on the ethnography and archaeology of the Americas. The museum is caretaker to over 1.2 million objects, some 900 linear feet of documents, 2,000 maps and site plans, and approximately 500,000 photographs. The museum is located at Divinity Avenue on the Harvard University campus. The museum is one of the four Harvard Museums of Science & Culture open to the public.
Harvard University is a private Ivy League research university in Cambridge, Massachusetts, with about 6,700 undergraduate students and about 15,250 post graduate students. Established in 1636 and named for its first benefactor, clergyman John Harvard, Harvard is the United States' oldest institution of higher learning, and its history, influence, and wealth have made it one of the world's most prestigious universities.
The "Museo Sitio Huellas de Acahualinca" is located at west of Managua, in the eponymous Acahualinca town. The museum was founded in 1953 by Nicaraguan scientist Leonor Martínez, later in 1989, was rescued, restored and fitted out with the support of "ASDI" and the Historical Museum of Sweden. In addition to footprints, the museum features a small collection of pottery and other items of archaeological interest from several sites in Nicaragua. Previously there were stone tools and a skull from León Viejo.
The Red Lady of Paviland is an Upper Paleolithic partial skeleton of a male dyed in red ochre and buried in Britain 33,000 BP. The bones were discovered in 1823 by William Buckland in an archaeological dig at Goat's Hole Cave — one of the limestone caves between Port Eynon and Rhossili on the Gower Peninsula, south Wales.
Kents Cavern is a cave system in Torquay, Devon, England. It is notable for its archaeological and geological features. The cave system is open to the public and has been a geological Site of Special Scientific Interest since 1952 and a Scheduled Ancient Monument since 1957.
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.
Archaeological science, also known as archaeometry, consists of the application of scientific techniques to the analysis of archaeological materials, to assist in dating the materials. It is related to methodologies of archaeology. Martinón-Torres and Killick distinguish ‘scientific archaeology’ from ‘archaeological science’. Martinón-Torres and Killick claim that ‘archaeological science’ has promoted the development of high-level theory in archaeology. However, Smith rejects both concepts of archaeological science because neither emphasize falsification or a search for causality.
Homo antecessor is a proposed archaic human species of the Lower Paleolithic, known to have been present in Western Europe between about 1.2 million and 0.8 million years ago (Mya). It was described in 1997 by Eudald Carbonell, Juan Luis Arsuaga and J. M. Bermúdez de Castro, who based on its "unique mix of modern and primitive traits" classified it as a previously unknown archaic human species.
Fa Hien Cave, also Pahiyangala Cave is situated in the district of Kalutara, Western Province, Sri Lanka and according to a rural legend, named after an alleged resident during historical times, namely Buddhist monk Faxian. However, there is no archaeological or historical evidence to support this legend. Nonetheless, the site is of archaeological significance as Late Pleistocene human fossilized skeletal remains were discovered in the cave's sediments during excavations in the 1960s, the 1980s and in 2013.
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. It is a museum dedicated to the appreciation and understanding of the Olduvai Gorge and Laetoli fossil sites.
Happisburgh is a village and civil parish in the English county of Norfolk. The village is on the coast, to the east of a north-south road, the B1159 from Bacton on the coast to Stalham. It is a nucleated village. The nearest substantial town is North Walsham 6 miles (10 km) to the west.
Footprints are the impressions or images left behind by a person walking or running. Hoofprints and pawprints are those left by animals with hooves or paws rather than feet, while "shoeprints" is the specific term for prints made by shoes. They may either be indentations in the ground or something placed onto the surface that was stuck to the bottom of the foot. A "trackway" is set of footprints in soft earth left by a life-form; animal tracks are the footprints, hoofprints, or pawprints of an animal.
The Ciampate del Diavolo is a locality near the extinct Roccamonfina volcano in northern Campania, Italy. It is named after a set of fossilised hominid footprints preserved in pyroclastic flow deposits that have been dated to around 350,000 years ago. They have been attributed to bipedal hominids, possibly Homo heidelbergensis, which is known to have inhabited the region at the time.
Amey's Eartham Pit is the original name for the internationally important Lower Palaeolithic archaeological site of Boxgrove in the English county of West Sussex. Today it is a disused, and largely infilled, sand and gravel quarry. Part of the site was designated a Site of Special Scientific Interest. When excavations began in 1982 flint tools 500,000 years old were discovered, which at that time was the oldest evidence of humans ever discovered in the UK. In 2005 flint tools 700,000 years old were discovered at Pakefield, and in 2010 flint tools at least 800,000 years old were discovered at Happisburgh. However, Boxgrove remains a site of international archaeological importance because of the discovery in 1994 and 1995 of 500,000-year-old early human fossils, which remain the oldest such fossils ever discovered in the UK. The other key Palaeolithic sites in the UK are Swanscombe, Pontnewydd, Kents Cavern, Paviland, and Gough's Cave. Boxgrove is also one of the oldest sites with direct evidence of hunting/butchering by humans.
The National Museum of Ethiopia (NME), also referred to as the Ethiopian National Museum, is a national museum in Ethiopia. It is located in the capital, Addis Ababa, near the Addis Ababa University's graduate school.
Hoedjiespunt is a Middle Pleistocene aged hominid fossil-bearing site on the West coast of South Africa, near the town of Saldanha Bay. The site is an ancient brown hyena lair dug into the side of a sand dune, located on a peninsula overlooking the Atlantic Ocean. The site became fossilized under a large calcrete formation around 280,000 years ago, at which time it was likely several kilometers from the ocean.
A fossil trackway is a type of trace fossil, a trackway made by an organism. Many fossil trackways were made by dinosaurs, early tetrapods, and other quadrupeds and bipeds on land. Marine organisms also made many ancient trackways.
Eve's footprint is the popular name for a set of fossilized footprints discovered on the shore of Langebaan Lagoon, South Africa in 1995. They are thought to be those of a female human and have been dated to approximately 117,000 years ago. This makes them the oldest known footprints of an anatomically-modern human. The estimated age of Eve's footprint means that the individual who left the tracks in the soil, thought to be female, would have lived within the current wide range of estimates for the date of Mitochondrial Eve.
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.
The Happisburgh footprints were a set of fossilized hominid footprints that date to the early Pleistocene, over 800,000 years ago. They were discovered in May 2013 in a newly uncovered sediment layer on a beach at Happisburgh in Norfolk, England, and carefully photographed in 3D before being destroyed by the tide shortly afterwards.
