Ordathspidotherium
''Orthaspidotherium'' was a European Paleocene genus of early herbivorous mammals of the family Pleuraspidotheriidae Pleuraspidotheriidae is a family of "condylarths" that lived in Europe from the Palaeocene to the Mid Eocene The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the seco .... It was included in the family Meniscotheriidae by Teilhard de Chardin in 1921-1922 and was subsequently separated into the family Pleuraspidotheriidae, before being placed in the family Phenacodontidae. The first complete skull of ''O. edwardsi'' was described in 2010, and the same paper once again places it in Pleuraspidotheriidae. A 2017 study further reiterates this view.

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification. In the Paleocene, the continents of the Northern Hemisphere were still connected v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Teilhard De Chardin
Pierre Teilhard de Chardin ( (); 1 May 1881 – 10 April 1955) was a French Jesuit priest, scientist, paleontologist, theologian, philosopher and teacher. He was Darwinian in outlook and the author of several influential theological and philosophical books. He took part in the discovery of Peking Man. He conceived the vitalist idea of the Omega Point. With Vladimir Vernadsky he developed the concept of the noosphere. In 1962, the Congregation for the Doctrine of the Faith condemned several of Teilhard's works based on their alleged ambiguities and doctrinal errors. Some eminent Catholic figures, including Pope Benedict XVI and Pope Francis, have made positive comments on some of his ideas since. The response to his writings by scientists has been divided. Teilhard served in World War I as a stretcher-bearer. He received several citations, and was awarded the Médaille militaire and the Legion of Honor, the highest French order of merit, both military and civil. Life Ea ...

Condylarths
Condylarthra is an informal group – previously considered an order – of extinct placental mammals, known primarily from the Paleocene and Eocene epochs. They are considered early, primitive ungulates. It is now largely considered to be a wastebasket taxon, having served as a dumping ground for classifying ungulates which had not been clearly established as part of either Perissodactyla or Cetartiodactyla, being composed thus of several unrelated lineages. Taxonomic history Condylarthra always was a problematic group. When Condylarthra was first described by , Phenacodontidae was the type and only family therein. , however, raised Condylarthra to an order and included a wide range of diverse placentals with generalized dentitions and postcranial skeletons. More recent researchers (i.e. post-WW2) have been more restrictive; either including only a limited number of taxa, or proposing that the term should be abandoned altogether. Due to their primitive characteristics condyla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Placental 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
