Fasciculus Retroflexus
''Fasciculus vesanus'' is an extinct species of stem-group ctenophores known from the Burgess Shale of British Columbia, Canada. It is dated to and belongs to middle Cambrian strata. The species is remarkable for its two sets of long and short comb rows, not seen in similar form elsewhere in the fossil record or among modern species.

Alberto Mario Simonetta
Alberto is the Romance version of the Latinized form (''Albertus'') of Germanic ''Albert''. It is used in Italian, Portuguese and Spanish. The diminutive forms are ''Albertito'' in Spain or ''Albertico'' in some parts of Latin America, Albertino in Italian as well as ''Tuco'' as a hypocorism. It derives from the name Adalberto which in turn derives from '' Athala'' (meaning noble) and ''Berth'' (meaning bright).

Ctenorhabdotus Capulus
''Ctenorhabdotus capulus'' is an extinct species of Ctenophora, ctenophore (or comb jelly), known from the Burgess shale in British Columbia, Canada. It is approximately 515 to 505 million years old and was equipped with 24 comb rows, three times as many as known from modern ctenophores. 5 specimens of ''Ctenorhabdotus'' are known from the Greater Phyllopod bed, where they comprise < 0.1% of the community.

Monotypic Ctenophore Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Prehistoric Ctenophore Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stromatoveris Psygmoglena
''Stromatoveris psygmoglena'' is a genus of basal petalonam from the Chengjiang deposits of Yunnan that was originally aligned with the fossil ''Charnia'' (strictly, the Charniomorpha) from the Ediacara biota. However, such an affinity is developmentally implausible and ''S. psygmoglena'' is now thought to be either a sessile basal ctenophore, or a sessile organism closely related to ctenophores. Nevertheless, a 2018 phylogenetic analysis by Jennifer Hoyal Cuthill and Jian Han indicated that ''Stromatoveris'' was a member of Animalia and closely related to ediacaran frond-like lifeforms. Distribution Cambrian of China China, officially the People's Republic of China (PRC), is a country in East Asia.

''Sinoascus paillatus'' is an extinct species of stem-group ctenophore, known from the Maotianshan shales of Yunnan, China. It is dated to Cambrian Stage 3 and belongs to late Early Cambrian strata. Fossil specimens are poorly preserved, providing little details, if any at all, about the anatomy of the comb rows.

Maotianshan Shales
The Maotianshan Shales are a series of Cambrian, Early Cambrian deposits in the Chiungchussu Formation, famous for their ''Lagerstätte, Konservat Lagerstätten'', deposits known for the exceptional preservation of fossilized organisms or traces. The Maotianshan Shales form one of some forty Cambrian fossil locations worldwide exhibiting exquisite preservation of rarely preserved, non-mineralized soft tissue, comparable to the fossils of the Burgess Shale. They take their name from Maotianshan Hill (, Literal meaning: Hat Sky Mountain) in Chengjiang County, Yunnan Province, China. The most famous assemblage of organisms are referred to as the Chengjiang biota for the multiple scattered fossil sites in Chengjiang. The age of the Chengjiang Lagerstätte is locally termed Qiongzhusian, a stage correlated to the late Atdabanian Stage in Siberian sequences of the middle of the Early Cambrian. The shales date to ≤. The shales also contain the slightly younger Guanshan biota from Mal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanioascus Canadensis
''Xanioascus canadensis'' is an extinct ctenophore, known from the Burgess Shale in British Columbia, Canada.

Fossil
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 ...
