Owadowia
''Owadowia'' is a genus of extinct thalassochelydian turtle from the Late Jurassic of Poland. The type and only species is ''Owadowia borsukbialynickae'', named by Szczygielski and colleagues in 2017 for a partial lower jaw, coracoid, ilium and femur from the early Tithonian Kcynia Formation. The limited material means that it is difficult to compare ''Owadowia'' to its relatives, and it may not be a unique taxon. The genus lacks the features diagnostic to its parent clade Thalassochelydia, has similarities to ''Solnhofia ''Solnhofia'' is a genus of extinct thalassochelydian turtle from the Late Jurassic of Germany. The type species is ''Solnhofia parsonsi'', named by Gaffney in 1975 for a partial skull and jaw from the early Tithonian of the Solnhofen Formation ...'' and '' Portlandemys'' as well as being a Late Jurassic marine turtle like the remainder of the group.

Thalassochelydia
Thalassochelydia is a clade of extinct marine turtles from the Late Jurassic and earliest Cretaceous of Europe and South America. The group is defined as including ''Eurysternum'', ''Plesiochelys'' and ''Thalassemys'' to the exclusion of ''Pelomedusa'', '' Testudo'' and '' Protostega''. While a clade uniting the families Eurysternidae, Plesiochelyidae and Thalassemydidae had been supported by phylogenetic evidence, a name was not given for the clade until 2017, when Jérémy Anquetin and colleagues coined Thalassochelydia. While inner relationships of the clade are so uncertain as to make the monophyly of the families questionable, the significant diversity of thalassochelydians makes using the potentially invalid terms useful to describe the different morphologies. The monophyly of Thalassochelydia was further supported by a later analysis by Serjocha Evers and Roger Benson in 2019, where the group, represented by '' Solnhofia'' and Plesiochelyidae was sister taxon to Sandown ...

Solnhofia
''Solnhofia'' is a genus of extinct thalassochelydian turtle from the Late Jurassic of Germany. The type species is ''Solnhofia parsonsi'', named by Gaffney in 1975 for a partial skull and jaw from the early Tithonian of the Solnhofen Formation in Bavaria. Additional material including a complete skeleton is known from the late Kimmeridgian of Switzerland and the Kimmeridgian/Tithonian of other deposits within Bavaria, and potentially also unprepared material from the Late Jurassic of France. The genus was referred to the family Eurysternidae by Anquetin and colleagues in 2017, which may represent an artificial grade of early thalassochelydians. In 2020 a new species ''Solnhofia brachyrhyncha'' was described from the Kimmeridigan aged Reuchenette Formation The Reuchenette Formation is a Jurassic geologic formation in Switzerland. It is Kimmeridgian in age and predominantly consists of well stratified limestone, with lithology variable both laterally and stratigraphically inc ...

Tithonian Genera
In the geological timescale, the Tithonian is the latest age of the Late Jurassic Epoch and the uppermost stage of the Upper Jurassic Series. It spans the time between 152.1 ± 4 Ma and 145.0 ± 4 Ma (million years ago). It is preceded by the Kimmeridgian and followed by the Berriasian (part of the Cretaceous).See for a detailed version of the geologic timescale Gradstein ''et al.'' (2004) Stratigraphic definitions The Tithonian was introduced in scientific literature by German stratigrapher Albert Oppel in 1865. The name Tithonian is unusual in geological stage names because it is derived from Greek mythology. Tithonus was the son of Laomedon of Troy and fell in love with Eos, the Greek goddess of dawn. His name was chosen by Albert Oppel for this stratigraphical stage because the Tithonian finds itself hand in hand with the dawn of the Cretaceous. The base of the Tithonian stage is at the base of the ammonite biozone of '' Hybonoticeras hybonotum''. A global reference profi ...

Prehistoric Turtle 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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kcynia Formation
Kcynia (german: Exin) is a town in Nakło County, Kuyavian-Pomeranian Voivodeship, Poland, with 4,712 inhabitants (2004). It is located in the Pałuki ethnographic region in the northern part of historic Greater Poland. History Kcynia started in the Middle Ages, with the rule of the founding Piast dynasty in Poland. In the 11th century, Polish ruler Władysław Herman built a church of St. Giles at the site.Tadeusz Pietrykowski, ''Z przeszłości Kcyni z okazji 666 rocznicy założenia miasta'', Kcynia, 1928, p. 16 (in Polish) In 1255 Kcynia was owned by Duke of Greater Poland Przemysł I. His brother, Duke Bolesław the Pious, in 1262 granted Kcynia town rights along with privileges similar to those enjoyed by Poznań and Gniezno.''Słownik geograficzny Królestwa Polskiego i innych krajów słowiańskich'', Tom III, Warszawa, 1882, p. 947 (in Polish) Kcynia was a royal town of the Polish Crown and a county seat in the Kalisz Voivodeship in the Greater Poland Province of the ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
