Lyme Regis, Dorset. Mary Anning [1] was born in Lyme Regis in Dorset, England, on 21 May 1799. [2] Her father, Richard Anning (c. 1766–1810), was a cabinetmaker and carpenter who supplemented his income by mining the coastal cliff-side fossil beds near the town, and selling his finds to tourists; her mother was Mary Moore (c. 1764–1842) known as Molly.

The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...
Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

Valsequillo, area of the findings. Hueyatlaco is an archeological site in the Valsequillo Basin near the city of Puebla, Mexico.After excavations in the 1960s, the site became notorious due to geochronologists' analyses, which have found wildly contradictory estimates for human habitation at Hueyatlaco dating from ca. 370,000 to 25,000 years before present (ybp).
The new study presents two additional lines of evidence for the older date range. It uses two entirely different materials found at the site, ancient conifer pollen and quartz grains.
The appearance of the first eukaryotic cells in the fossil record were relatively followed by evidence of complex multicellular life. Rocks in Nevada dating back to a billion years ago preserve trace fossils left behind by worms as they burrowed below the sediment. [3] Other complex Precambrian life forms were preserved in North Carolina [4 ...
The oldest known surviving tombstone in the United States is an elaborate display of wealth — an intricately carved slab of black limestone initially laid in the floor of the second church of ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
