Taveirosaurus
''Taveirosaurus'' (meaning " Taveiro lizard") is a genus of possibly eutriconodontan mammal from the Late Cretaceous Argilas de Aveiro Formation of Portugal, and also Laño, Spain. The genus is based solely on teeth, and the type species is ''T. costai''. Discovery and naming In 1968, Miguel Telles Antunes and Giuseppe Manuppella uncovered fossils at the ''Cerâmica do Mondego'' quarry near Taveiro, a village in Portugal, southwest of Coimbra. Among them were a number of low triangular teeth of a herbivorous dinosaur. In 1991 these were named and described by Telles Antunes and Denise Sigogneau-Russell as the type species, ''Taveirosaurus costai''. The generic name refers to Taveiro. The specific name honours the Portuguese geologist João Carrington da Costa.M. Telles Antunes & D.

Trimucrodon
''Trimucrodon'' is a genus of ornithischian dinosaur from the Late Jurassic Lourinhã Formation of Portugal. The type, and currently only, species is ''T. cuneatus''. Discovery and naming Three isolated teeth found at the Porto Dinheiro (or Pinhiero) locality in the Lisboa District of Portugal were given the name in 1973 by Richard A. Thulborn, derived from the Latin words for "three" and a dagger point, and , and the Ancient Greek word for "tooth". The only species in the taxon is ''Trimucrodon cuneatus'', taken from the wedge shape of the teeth. Though the unit the specimens came from was originally unnamed, it was referred to the Alcobaça, and then Lourinhã Formations, specifically the late Kimmeridgian Amoreira–Porto Novo Member. The type specimen, uncovered between 1962 and 1967 by German zoologist and paleontologist Georg Krusat, is distinguished by prominent denticles at the front and rear ends of the crown, and comes from an individual under long.G.

Eutriconodonta
Eutriconodonta is an order (biology), order of early mammals. Eutriconodonts existed in Asia (including Insular India, pre-contact India), Africa, Europe, North America, North and South America during the Jurassic and the Cretaceous periods. The order was named by Kermack ''et al.'' in 1973 as a replacement name for the paraphyletic Triconodonta. Traditionally seen as the classical Mesozoic small mammalian insectivores, discoveries over the years have shown them to be among the best examples of the diversity of mammals in this time period, including a vast variety of bodyplans, ecological niches and locomotion methods. Classification "Triconodonta" had long been used as the name for an order of early mammals which were close relatives of the ancestors of all present-day mammals, characterized by molar teeth with three main cusps on a crown that were arranged in a row. The group originally included only the family Triconodontidae and taxa that were later assigned to the separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithischia
Ornithischia () is an extinct clade of mainly herbivorous dinosaurs characterized by a pelvic structure superficially similar to that of birds. The name ''Ornithischia'', or "bird-hipped", reflects this similarity and is derived from the Greek stem ' (), meaning "bird", and ' (), meaning "hip". However, as theropod dinosaurs, birds are only distantly related to this group. Ornithischians with well known anatomical adaptations include the ceratopsians or "horn-faced" dinosaurs (e.g. ''Triceratops''), the pachycephalosaurs or "thick-headed" dinosaurs, the armored dinosaurs ( Thyreophora) such as stegosaurs and ankylosaurs, and the ornithopods. There is strong evidence that certain groups of ornithischians lived in herds, often segregated by age group, with juveniles forming their own flocks separate from adults. Some were at least partially covered in filamentous (hair- or feather- like) pelts, and there is much debate over whether these filaments found in specimens of '' Ti ...

Laño
Laño () is a hamlet and '' concejo'' (a small administrative subdivision) in Condado de Treviño within the Treviño enclave; which is administratively part of the Spanish province of Burgos, but which is completely surrounded by the territory of the Basque country province of Álava. It is best known for the fossils of extinct vertebrates dating from around 70 million years before present which have been found there. Las Gobas, a site of ancient artificial caves from the 7th to the 13th century CE, is located just north of the village. Palaeontology The Paleontology Unit of the University of the Basque Country and other scientists have studied the fossil record at Laño. The fossils are from the late Cretaceous ( late Campanian to lower Maastrichtian). It has been inferred that there was then a braided riverbed at the site, that the sea was nearby, and that the climate was tropical or sub-tropical.
