Coltraneia Frontal 2
''Coltraneia'' is a genus of trilobites, that lived during the upper Emsian and lower Eifelian, and has been found in Algeria, France, Germany, Morocco and Spain. Description The frontal lobe of the central raised area of the headshield (or glabella) is rounded. The furrow defining the glabella is curved behind the frontal lobe. Both lobes directly behind the frontal lobe (L3 and L2) are more elevated than the lobe (L1) just in front of the occipital ring (L0). All sighted phacopina have schizochroal eyes, but in ''Coltraneia'' these are particularly large with 13–14 lenses in each of the vertical rows (or dorsoventral file) at midlength. The front of these eyes almost touches the furrow separating the frontal from the following lobe, while the back of the eyes touch the posterior border furrow. The axis of the tailshield (or pygidium) has 13 to 15 rings, and is constricted between the 6th and 7th rings. In the pleural region to the side of the pygidial axis, 8–11 segments ...

Emsian
The Emsian is one of three faunal stages in the Early Devonian Epoch. It lasted from 410.62 ±1.95 million years ago to 393.47 ±0.99 million years ago. It was preceded by the Pragian Stage and followed by the Eifelian Stage. It is named after the Ems river in Germany.

In North America the Emsian Stage is represented by Sawkill or Sawkillian time. Biological events During this period, earliest known agoniatitid ammonoid fossils began appearing within this stage after first appearing in previous stage and began to evolutionarily radiate within this stage, in which a new ammonoid or ...

Fossils Of Algeria
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of ''Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. The ob ...

Eifelian Extinctions
The Eifelian is the first of two faunal stages in the Middle Devonian Epoch. It lasted from 393.3 ± 1.2 million years ago to 387.7 ± 0.8 million years ago. It was preceded by the Emsian Stage and followed by the Givetian Stage. North American subdivisions of the Eifelian Stage include Southwood, and part of Cazenovia (or Cazenovian). Name and definition The Eifelian is named after the Eifel Mountains of Western Germany, which exposed the GSSP section at the Wetteldorf Richtschnitt outcrop. The base of the Eifelian is defined by the start of the '' Polygnathus partitus'' conodont zone. This layer lies within the Upper Heisdorf Formation, below the base of the Lauch Formation. Major events The earliest forest is known from the Eifelian stage. Cladoxylopsid trees including ''Calamophyton'' and other plants have formed the forest landscape in what is now England. Extinctions The end of the Eifelian was marked by a biological crisis known as the Kačák Event, a two-part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Devonian Trilobites Of Europe
The Devonian ( ) is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago ( Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of life on land occurred during the Devonian, as free- sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants ( pteridospermatophytes) appeared. This rapid evolution and colonization process, which had begun during the Silurian, is known as the Silurian-Devonian Terrestrial Revolu ...

John Coltrane
John William Coltrane (September 23, 1926 – July 17, 1967) was an American jazz saxophonist, bandleader and composer. He is among the most influential and acclaimed figures in the Jazz#Post-war jazz, history of jazz and 20th-century music. Born and raised in North Carolina, after graduating from high school Coltrane moved to Philadelphia, where he studied music. Working in the bebop and hard bop idioms early in his career, Coltrane helped pioneer the use of Modal jazz, modes and was one of the players at the forefront of free jazz. He led at least fifty recording sessions and appeared on many albums by other musicians, including trumpeter Miles Davis and pianist Thelonious Monk. Over the course of his career, Coltrane's music took on an increasingly spiritual dimension, as exemplified on his most acclaimed album ''A Love Supreme'' (1965) and others. Decades after his death, Coltrane remains influential, and he has received numerous posthumous awards, including a Pulitzer ...
