Websteroprion
''Websteroprion'' ("Webster's saw") is a genus of eunicidan polychaete that lived during the middle Devonian period in what is now Canada. It contains a single species, ''W. armstrongi'', recovered from the Kwataboahegan Formation. Etymology The genus was named after the bassist Alex Webster of the death metal band Cannibal Corpse. Description ''Websteroprion'' is known from the maxillae of several individuals in one location. These maxillae reaching in length, with one incomplete specimen that supposed to be bigger in full size. These are the largest jaws of any fossil polychaete. A larger fossil jaw had been reported in 1934Eller E. R. Annelid jaws from the Hamilton group of Ontario County, New York. Ann. Carnegie Mus. 24, 51–56 (1934). but that specimen is too undiagnostic so it regarded as a ''nomen dubium''. Referencing the jaw to body size ratio of other polychaetes, ''Websteroprion'' could have grown to long, though the exact size is unknown without soft tissue p ...

Alex Webster
Alex Webster (born 1969) is an American bass player who is best known as a member of the death metal band Cannibal Corpse. He is one of two remaining members of the original lineup of the band, along with drummer Paul Mazurkiewicz. He is also the bassist for the band Blotted Science and the supergroup Conquering Dystopia. Before Cannibal Corpse was formed, he was part of Beyond Death. Musical biography Webster was born in Akron, New York. When describing his relationship with music, he has stated "I just always liked music since I was a little kid. Music was always a soundtrack in my head to things going on in my life. I always wanted to play. I wanted to play drums when I was about three. I made a drum out of an old butter container and hit it with tinker toys. I was going to make music. Most people who are musicians didn't have to have anyone tell them to do it. I would never push music on someone, because it is something that doesn't need to be pushed. If you're going ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eunicida
Eunicida is an order of polychaete worms. Characteristics Members of this order have an elongated, segmented body and a distinct head, normally with a separate peristomium and prostomium. Many, but not all, live in tubes which vary from a mucous sheath to a tough, horny casing. The palps vary from globular to cylindrical and there are from 0 to 7 antennae, usually smooth but occasionally jointed. There is a muscular pharynx with a dorsal pair of mandibles and a set of ventral, toothed, maxillary plates. Some species have tentacular cirri and all have unbranched parapodia. In some species, dorsal cirri, branchiae, ventral cirri and chaetae occur, but not in others. Natural History Museum. Retrieved 2012-01-17. Fossil record The |
Cannibal Corpse
Cannibal Corpse is an American death metal band formed in Buffalo, New York in 1988, now based out of Tampa, Florida. The band has released fifteen studio albums, two box sets, four video albums, and two live albums. The band has had little radio or television exposure throughout its existence, although a cult following began to build with the releases of their early albums, including ''Butchered at Birth'' (1991) and ''Tomb of the Mutilated'' (1992).

Fossils Of Canada
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''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolut ...

Devonian Canada
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating al ...

Eunice Aphroditois
''Eunice aphroditois'' is a benthic bristle worm of warm marine waters. It lives mainly in the Atlantic Ocean, but can also be found in the Indo-Pacific. It ranges in length from less than to . Its iridescent cuticle produces a wide range of colors, from black to purple. This species is an ambush-predator; it hunts by burrowing its whole body in soft sediment on the ocean floor and waiting until its antennae detect prey. It then strikes with its sharp mouthparts. It may also be found among coral reefs. ''E. aphroditois'' is commonly known as the ''sand-striker'' or ''bobbit-worm''; the latter name is from the John and Lorena Bobbitt case. Description These ambush predators have no eyes and five antennae on their head that are used to sense prey. The body is covered by a hard exoskeleton. The mandibles can be retracted inside the body and are responsible for striking and stunning prey; they are capable of snapping some prey in half. Typically, ''E. aphroditois'' ranges from dee ...

Onuphidae
The Onuphidae are a family of polychaete worms. Characteristics Most onuphids have tubes. Some live semisubmerged in the substrate, but others carry their tubes around, and they can all rebuild their tubes if necessary. The tubes, thin and parchment-like, are formed of bits of shell and sand, with plant debris, stuck together with mucus. The onuphids are all omnivorous scavengers, feeding on animal and vegetable debris.Onuphidae Marine Errant Polychaetes in Hong Kong. Retrieved 2012-01-16. A Guide To Singapore Polychaetes. Retrieved 2012-01-16. The prostomium has two short frontal antennae, two globular palps and five main antennae. The mandibles are large and the maxillae have several pairs of plates edged with fine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eunicidae
Eunicidae is a family of marine polychaetes (bristle worms). The family comprises marine annelids distributed in diverse benthic habitats across Oceania, Europe, South America, North America, Asia and Africa. The Eunicid anatomy typically consists of a pair of appendages near the mouth (mandibles) and complex sets of muscular structures on the head (maxillae) in an eversible pharynx. One of the most conspicuous of the eunicids is the giant, dark-purple, iridescent " Bobbit worm" (''Eunice aphroditois''), a bristle worm found at low tide under boulders on southern Australian shores. Its robust, muscular body can be as long as 2 m. Eunicidae jaws are known from as far back as Ordovician sediments. Cultural tradition surrounds Palola worm (''Palola viridis'') reproductive cycles in the South Pacific Islands. Eunicidae are economically valuable as bait in both recreational and commercial fishing. Commercial bait-farming of Eunicidae can have adverse ecological impacts. Bait-far ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Broadcasting Corporation
The Canadian Broadcasting Corporation (french: Société Radio-Canada), branded as CBC/Radio-Canada, is a Canadian public broadcaster for both radio and television. It is a federal Crown corporation that receives funding from the government. The English- and French-language service units of the corporation are commonly known as CBC and Radio-Canada, respectively. Although some local stations in Canada predate the CBC's founding, CBC is the oldest existing broadcasting network in Canada. The CBC was established on November 2, 1936. The CBC operates four terrestrial radio networks: The English-language CBC Radio One and CBC Music, and the French-language Ici Radio-Canada Première and Ici Musique. (International radio service Radio Canada International historically transmitted via shortwave radio, but since 2012 its content is only available as podcasts on its website.) The CBC also operates two terrestrial television networks, the English-language CBC Television and the Frenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emsian
The Emsian is one of three faunal stages in the Early Devonian Epoch. It lasted from 407.6 ± 2.6 million years ago to 393.3 ± 1.2 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. The GSSP is located in the Zinzil'ban Gorge in the Kitab State Geological Reserve of Uzbekistan, above the contact with the Madmon Formation. 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 order Goniatitida rises in the end of Zlichovian stage (Siberian representation; corresponds to early Eifelian and after the end of Early Devonian, before 391.9 mya). Later agoniatitid ammonoids would die out in the Taghanic event in the upper middle Givetian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eifelian
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. Extinctions The end of the Eifelian was marked by a biological crisis known as the Kačák Event, a two-part interval of extinction which led to ecological turnover among ammonoids, conodonts, and other free-swimming animals. In deep marine waters, the event is indicated by anoxic black shales. Ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
