Exempel på hur man kan använda AMNIOTES i en mening

• In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals).
• The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids.
• Traditionally, the Anapsida are considered the most primitive subclass of amniotes, the ancestral stock from which Synapsida and Diapsida evolved, making anapsids paraphyletic.
• Tetrapods include all extant and extinct amphibians and amniotes, with the latter in turn evolving into two major clades, the sauropsids (reptiles, including dinosaurs and therefore birds) and synapsids (extinct pelycosaurs, therapsids and all extant mammals, including humans).
• A claw is a curved, pointed appendage found at the end of a toe or finger in most amniotes (mammals, reptiles, birds).
• In humans and other amniotes (mammals, birds and reptiles), most of these substances leave the body as urine and to some degree exhalation, mammals also expel them through sweating.
• The chorion is the outermost fetal membrane around the embryo in mammals, birds and reptiles (amniotes).
• The arch is typical of Synapsida ("fused arch"), a clade of amniotes that includes mammals and their extinct relatives, such as Moschops and Dimetrodon.
• Sauropsida (Greek for "lizard faces") is a clade of amniotes, broadly equivalent to the class Reptilia, though typically used in a broader sense to also include extinct stem-group relatives of modern reptiles and birds (which, as theropod dinosaurs, are nested within reptiles as more closely related to crocodilians than to lizards or turtles).
• Romeriscus is a genus from the early Pennsylvanian (Late Carboniferous) initially described as the oldest known amniote, but this is because limnoscelids were, at that time, considered amniotes by some authors.
• The allantois, along with the amnion, chorion, and yolk sac (other extraembryonic membranes), identify humans and other mammals, birds, and reptiles as amniotes.
• A genital tubercle, phallic tubercle, or clitorophallic structure is a body of tissue present in the development of the reproductive system of amniotes.
• In amniotes, the cells of the morula are at first closely aggregated, but soon they become arranged into an outer or peripheral layer, the trophoblast, which does not contribute to the formation of the embryo proper, and an inner cell mass, from which the embryo is developed.
• As the exact phylogenetic position of Lissamphibia within Tetrapoda remains uncertain, it also remains controversial which fossil tetrapods are more closely related to amniotes than to lissamphibians, and thus, which ones of them were reptiliomorphs in any meaning of the word.
• They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.
• Gauthier, Kluge and Rowe (1988) defined Anthracosauria as a clade including "Amniota plus all other tetrapods that are more closely related to amniotes than they are to amphibians" (Amphibia in turn was defined by these authors as a clade including Lissamphibia and those tetrapods that are more closely related to lissamphibians than they are to amniotes).
• During this time, he studied tetrapod remains from the Pennsylvanian lycopod “tree stumps” at Joggins, Nova Scotia (a variety of temnospondyls, microsaurs, and basal amniotes).
• Sperm cells form during the process known as spermatogenesis, which in amniotes (reptiles and mammals) takes place in the seminiferous tubules of the testicles.
• Unlike in other amniotes, the egg tooth of squamates is an actual tooth which develops from the premaxilla.
• describe two isoforms of succinyl-CoA synthetase in amniotes, one that specifies synthesis of ATP, and one that synthesises GTP.
