These are proposed species names for fossils from about 1. 9 – 1. 6 Ma, whose relation to Homo habilis is not yet clear.

These types of fossil are called trace fossils ( or ichnofossils ), as opposed to body fossils.

These fossils serve as a reminder that taxonomic divisions are human constructs that have been imposed in hindsight on a continuum of variation.

These fossils help scientists to date the core and to understand the depositional environment in which the rock units formed.

These dates coincide with the hypothesis derived from fossils that the walrus evolved from a tropical or subtropical ancestor that became isolated in the Atlantic Ocean and gradually adapted to colder conditions in the Arctic.

These were fossils with colourful local names such as " snake-stones " ( ammonites ), " devil's fingers " ( belemnites ), and " verteberries " ( vertebrae ), to which were sometimes attributed medicinal and mystical properties.

These discoveries also played a key role in the development of a new discipline of geohistorical analysis within geology in the 1820s that sought to understand the history of the earth by using evidence from fossils to reconstruct extinct organisms and the environments in which they lived.

These fossils appear to belong to the crown group, and illustrate that sipunculans have changed little since the early Cambrian.

These cliffs, generally known as Calvert Cliffs, are famous for their fossils, especially fossilized shark teeth which are commonly found washed up on the beaches next to the cliffs.

These soft-bodied fossils are the first record of multicellular life.

These would be the first of many fossils excavated from the La Brea Tar Pits.

These non-volcanic rock beds are rich with fossils of prehistoric marine life once native to the inland sea that covered the area some 280 million years ago, ranging from well preserved molluscan shells, to small fish.

These fossils are thought to be 551 to 635 million years old ( belonging to the Neoproterozoic era ).

These fossils closely resemble the genus Allomyces.

These fossils presently reside in the collections of Museo de La Plata and Museo Paleontológico Egidio Feruglio, both in Argentina.

These fossils range from the Jurassic to the Cretaceous periods.

These fossils were first found in 1930.

These formations contain important fossils of animals such as the extinct Cape lion and also provide evidence that stone-age people hunted here tens of thousands of years ago.

These would be the first of many fossils excavated from the La Brea Tar Pits.

These fossils were packaged in tree boxes at the construction site and moved to a compound behind Pit 91, on Page museum property so that construction could continue.

These fossils help define a picture of what is thought to have been a cooler, moister climate in the Los Angeles basin during the glacial age.

These limestones contain the aboundant fossils of shallow marine foraminifera, coral, mollusks, and algae.

These fossils serve as a reminder that taxonomic divisions are human constructs that have been imposed in hindsight on a continuum of variation.

These became known as Syro-Hittite states.

These were commonly referred to as " Arians " due to their rejection of the Trinity, though in fact the Socinians, as they were later known, went further than Arius to the position of Photinus.

These holes collectively make up what is known as the selenizone which form as the shell grows.

These brokers came to be known as the curbstone brokers, as they conducted their auctions out in the street.

These are the known ancestors of Afonso Henriques, going back five generations.

These include Hindu astrology ( also known as " Indian astrology " and in modern times referred to as " Vedic astrology ") and Chinese astrology, both of which have influenced the world's cultural history.

These are the first pure landscape studies known in Western art.

These are the smallest of the AC enzyme classes ; the AC-IV from Yersinia is a dimer of 19 kDa subunits with no known regulatory components.

These are of the type known as " inginocchiata ", " kneeling " on two brackets.

These ions, under the influence of the electric field, are accelerated into the cathode surface containing the sample, bombarding the sample and causing neutral sample atom ejection through the process known as sputtering.

These compounds, e. g. calicheamicin, are some of the most aggressive antitumor drugs known, so much so that the ene-diyne subunit is sometimes referred to as a " warhead.

These 10 residues are then known as angiotensin I. Angiotensin converting enzyme ( ACE ) then removes a further two residues which converts angiotensin I into angiotensin II.

These 390 square kilometres of limestone-covered landscape is also known for its underground caverns.

These securities, known as ADRs ( American Depositary Receipt ) or GDRs ( Global Depositary Receipt ) depending on where they are issued, are typically considered " foreign " and therefore trade at a lower value when first released.

These poles and zone-lines, whilst inducing fluctuations in data density in the reconstructed datasets, which can prove problematic during post-analysis, are critical for determining information such as angular magnification, as the crystallographic relationships between features are typically well known.

These are sometimes known as signature bridges.

These Orkhon inscriptions are the first known texts in the Old Turkic language.

These became known as the Negro Leagues, though these leagues never had any formal overall structure comparable to the Major Leagues.

These models were known as dwarf safeties, or safety bicycles, for their lower seat height and better weight distribution ( although without pneumatic tires the ride of the smaller-wheeled bicycle would be much rougher than that of the larger-wheeled variety ).

These events are usually separated by periods of " normal " mood ; but, in some individuals, depression and mania may rapidly alternate, which is known as rapid cycling.

These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam.

These linear combinations are also known as Bessel functions of the third kind ; they are two linearly independent solutions of Bessel's differential equation.

These land parcels were then handed to Dutch planters known as perkeniers of which 34 were on Lontar, 31 on Ai and 3 on Neira.

These styles are known because of the importance of Irish and Scottish people in the English speaking world, especially in the United States, where they had a profound impact on American music, particularly bluegrass and country music.

These families are now known to be only distantly related.
