It is conventionally ranked as a Subclass biology subclass within the mammal s. Most of the animals in this group are extinct. The egg laying monotremes are known from fossils of the Cretaceous and Cenozoic periods they are represented today by the platypus and several species of echidna . The names Prototheria, Metatheria and Eutheria meaning first beasts , changed beasts , and true beasts refer to the three mammalian groupings which have living representatives. Each of the three may be defined as a total clade containing a living crown group respectively the Monotremata, Marsupialia and Placentalia plus any fossil species which are more closely related to that crown group than to any other living animals.

italictitle Taxobox name Akidolestes cifellii fossil range Early Cretaceous regnum Animalia phylum Chordata classis Mammal ia unranked ordo Trechnotheria ordo Symmetrodonta superfamilia Spalacotherioidea familia Spalacotheriidae genus Akidolestes genus authority Li and Luo, 2006 species A. cifellii binomial Akidolestes cifellii binomial authority Li and Luo, 2006 Akidolestes cifellii is an extinct mammal which dates to the early Cretaceous period, 124.6 million years ago. It is part of the Yixian formation in Liaoning , China . The description is based on a nearly complete skeleton , partially complete skull , and an impression. It is notable in that it displays characteristics of monotremes but appears to be more related to modern theria n mammals. Akidolestes has no modern relatives. It is an early offshoot of mammal related to therians the subclass containing marsupial s and placental s . It clearly belongs within a group of theriiform mammals known as the Spalacotherioidea . Unlike other members of this Taxonomic rank superfamily , however, Akidolestes has some very prototheria n features. Cervical rib s are present, a condition previously known only from monotremes and basal mammals such as Repenomamus and Fruitafossor . Akidolestes is also monotreme like in the shape of its pubis bone pubis , and in aspects of hindlimb posture. Overall, however, other aspects of the appendicular skeleton , tooth dental characters, and cranial characters strongly suggest that Akidolestes falls well within the Spalacotherioidea and does represent an early branch of theriiform mammal. Luo and Li suggest that these primitive characters were homoplasy reacquired in this group as a result of either Convergent evolution convergence or through a modification of a developmental pathway to a prior state. The genus name, Akidolestes , is derived from akido , Greek language Greek for point, and lestes , Greek for thief. Akido refers to the pointed Rostrum anatomy snout and lestes is a com ... more details
File DMDQ.jpg thumb Right 250px View from the Dry Mesa Dinosaur Quarry overlooking Escalante Canyon The Dry Mesa Dinosaur Quarry is situated in southwestern Colorado , USA , near the town of Delta, Colorado Delta . Its geology forms a part of the Morrison Formation and has famously yielded a great diversity of animal remains from the Jurassic Period geology Period , among them Ceratosaurus , Supersaurus , and Torvosaurus . The quarry is found within the Uncompahgre National Forest . History In 1971, a large theropod phalanx bones phalanx Torvosaurus tanneri http dinosaurjim.com html torvosaurus tanneri.html was discovered at Dry Mesa by Daniel and Vivian Jones http dinosaurjim.com html eddie vivian jones.html of Delta, Colorado. The find was reported to James A. Jensen http dinosaurjim.com html dry mesa quarry.html of Brigham Young University BYU who commenced quarrying operations in 1972. Under the direction of the BYU Earth Science Museum, the quarry has been excavated for 13 field seasons. Approximately 4000 bones have been collected, making it one of the most prolific dinosaur producing accumulations in the Morrison Formation . Thirty vertebrate genera are represented in the quarry including dinosaur s, a pterosaur , crocodile, turtle, lungfish , and a prototheria n mammal. Twenty three genera of dinosaurs have been found in the quarry distinguishing it as the most diverse Jurassic dinosaur assemblage. The quarry is especially recognized for its large sauropods, among which Supersaurus vivianae http dinosaurjim.com html supersaurus viviani.html and Supersaurus Ultrasaurus mcintoshi http dinosaurjim.com html ultrasaurus mcintoshi.html are the most celebrated finds Richmond and Morris, 1999 .

The short beaked echidna is covered in fur and spines, and has a distinctive snout and a specialized tongue, which it uses to catch its prey at a great speed. Like the other extant monotreme s, the short beaked echidna lays egg biology eggs the monotremes are the only group of mammal s to do so. This echidna has extremely strong front limbs and claws due to its mechanical advantage , which allows it to burrow quickly with great power. As it needs to be able to survive underground, it has a great tolerance to high levels of carbon dioxide and a lack of oxygen. It has no weapons or fighting ability, and repels predators by curling into a ball and deterring opponent with its spines. The echidna lacks the ability to sweat and cannot deal with heat well, so it tends to avoid daytime activity in hot weather it can swim if needed. The snout has mechanical and electroreceptors that help it to detect what is around it. During the winter, it goes into deep torpor and ... more details
