Lanthanosuchidae is a family of procolophonomorph parareptile Parareptilia ("near-reptiles") is an extinct group of Basal (phylogenetics), basal Sauropsida, sauropsids ("Reptile, reptiles"), traditionally considered the sister taxon to Eureptilia (the group that likely contains all living reptiles and birds ...s that lived 268–255 million years ago.

Lanthaniscus
''Lanthaniscus'' is an extinct genus of lanthanosuchoid ankyramorph parareptile known from the Guadalupian epoch (Late Roadian to latest Wordian age) of Eastern Europe, Russia. ''Lanthaniscus'' was first named by M. F. Ivakhnenko in 1980 and the type species is ''Lanthaniscus efremovi''. ''L. efremovi'' was originally described on the basis of the holotype PIN 3706/9 from Peza-1 locality, Krasnoshchel' Formation, of Arkhangelsk. Various authors had assigned it to the family Lanthanosuchidae Lanthanosuchidae is a family of procolophonomorph parareptile Parareptilia ("near-reptiles") is an extinct group of Basal (phylogenetics), basal Sauropsida, sauropsids ("Reptile, reptiles"), traditionally considered the sister taxon to Eurept ...;deBraga, M. and Rieppel, O.

Permian
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ivan Antonovich Efremov
Ivan Antonovich (Antipovich) Yefremov, sometimes Efremov (; 23 April 1908 – 5 October 1972) was a Soviet paleontologist, science-fiction author and social thinker. He founded taphonomy, the study of fossilization patterns. Biography He was born in the village of Vyritsa in Saint Petersburg Governorate on 23 April 1908. His parents divorced during the Russian Revolution. His mother married a Red Army commander and left the children in Kherson to be cared for by an aunt who soon died of typhus. Yefremov survived on his own for some time, after which he joined a Red Army unit as a "son of the regiment" and went to Perekop with it. In 1921, he was discharged and went to Petrograd (now Saint Petersburg) to study. He completed his education there while combining his studies with a variety of odd jobs. He later commented that "the Revolution was also my own liberation from philistinism" (). Academic career In 1956, due to the influence of academician Petr Sushkin, he became ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Procolophonomorpha
Procolophonomorpha is an order containing most parareptiles. Many papers have applied various definitions to the name, though most of these definitions have since been considered synonymous with modern parareptile clades such as Ankyramorpha and Procolophonia. The current definition of Procolophonomorpha, as defined by Modesto, Scott, & Reisz (2009), is that of as a stem-based group containing '' Procolophon'' and all taxa more closely related to it than to '' Milleretta''. It constitutes a diverse assemblage that includes a number of lizard-like forms, as well as more diverse types such as the pareiasaurs. Lee 1995, 1996, 1997 argues that turtles evolved from pareiasaurs, but this view is no longer considered likely. Rieppel and deBraga 1996 and deBraga and Rieppel, 1997 argue that turtles evolved from sauropterygians, and there is both molecular and fossil (''Pappochelys'') evidence for the origin of turtles among diapsid reptiles.

Parareptile
Parareptilia ("near-reptiles") is an extinct group of Basal (phylogenetics), basal Sauropsida, sauropsids ("Reptile, reptiles"), traditionally considered the sister taxon to Eureptilia (the group that likely contains all living reptiles and birds). Parareptiles first arose near the end of the Carboniferous, Carboniferous period and achieved their highest diversity during the Permian, Permian period. Several ecological innovations were first accomplished by parareptiles among reptiles. These include the first reptiles to return to marine ecosystems (mesosaurs), the first Bipedalism, bipedal reptiles (Bolosauridae, bolosaurids such as ''Eudibamus''), the first reptiles with advanced hearing systems (Nycteroleteridae, nycteroleterids and others), and the first large herbivorous reptiles (the pareiasaurs). The only parareptiles to survive into the Triassic, Triassic period were the Procolophonoidea, procolophonoids, a group of small generalists, omnivores, and herbivores. The largest f ...
