The Ptychitidae is a family of ceratitid ammonites (ammonites sensu lato). They are combined with the Eosagenitidae and Sturiidae in the superfamily Ptychitoidea.
Ptychitid genera have compressed, involute shells in which the inner whorls are covered by the outermost, that may be ribbed or smooth, and ammonitic sutures with secondary elements.
Ammon was an ancient Semitic-speaking kingdom occupying the east of the Jordan River, between the torrent valleys of Arnon and Jabbok, in present-day Jordan. The chief city of the country was Rabbah or Rabbat Ammon, site of the modern city of Amman, Jordan's capital. Milcom and Molech are named in the Hebrew Bible as the gods of Ammon. The people of this kingdom are called Children of Ammon or Ammonites.
Ammonoids are extinct spiral shelled cephalopods comprising the subclass Ammonoidea. They are more closely related to living coleoids than they are to shelled nautiloids. The earliest ammonoids appeared during the Devonian, with the last species vanishing during or soon after the Cretaceous–Paleogene extinction event. They are often called ammonites, which is most frequently used for members of the order Ammonitida, the only remaining group of ammonoids from the Jurassic up until their extinction.
Ammonite is the extinct Canaanite language of the Ammonite people mentioned in the Bible, who used to live in modern-day Jordan, and after whom its capital Amman is named. Only fragments of their language survive—chiefly the 9th century BC Amman Citadel Inscription, the 7th–6th century BC Tel Siran bronze bottle, and a few ostraca. As far as can be determined from the small corpus, it was extremely similar to Biblical Hebrew, with some possible Aramaic influence including the use of the verb ‘bd (עבד) instead of the more common Biblical Hebrew ‘śh (עשה) for 'make'. The only other notable difference with Biblical Hebrew is the sporadic retention of feminine singular -t Ammonite also appears to have possessed largely typical correspondences of diphthongs, with words such as ywmt both preserving and showing a shift to, and other words such as yn exhibiting a shift of to ē much like Hebrew.
The Barremian is an age in the geologic timescale between 125.77 Ma and 121.4 ± 1.0 Ma It is a subdivision of the Early Cretaceous Epoch. It is preceded by the Hauterivian and followed by the Aptian Stage.
Alcide Charles Victor Marie Dessalines d'Orbigny was a French naturalist who made major contributions in many areas, including zoology, palaeontology, geology, archaeology and anthropology.
Ammonitida or "True ammonites" are an order of ammonoid cephalopods that lived from the Jurassic through Paleocene time periods, commonly with intricate ammonitic sutures.
The Toarcian is, in the ICS' geologic timescale, an age and stage in the Early or Lower Jurassic. It spans the time between 184.2 Ma and 174.7 ±0.8 Ma. It follows the Pliensbachian and is followed by the Aalenian.
In the geologic timescale, the Anisian is the lower stage or earliest age of the Middle Triassic series or epoch and lasted from 247.2 million years ago until 242 million years ago. The Anisian Age succeeds the Olenekian Age and precedes the Ladinian Age.
In the geological timescale, the Berriasian is an age/stage of the Early/Lower Cretaceous. It is the oldest subdivision in the entire Cretaceous. It has been taken to span the time between 145.0 ± 4.0 Ma and 139.8 ± 3.0 Ma. The Berriasian succeeds the Tithonian and precedes the Valanginian.
In the geologic timescale, the Valanginian is an age or stage of the Early or Lower Cretaceous. It spans between 139.8 ± 3.0 Ma and 132.6 ± 2.0 Ma. The Valanginian Stage succeeds the Berriasian Stage of the Lower Cretaceous and precedes the Hauterivian Stage of the Lower Cretaceous.
The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 to 72.1 million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian.
The Hettangian is the earliest age and lowest stage of the Jurassic Period of the geologic timescale. It spans the time between 201.3 ± 0.2 Ma and 199.3 ± 0.3 Ma. The Hettangian follows the Rhaetian and is followed by the Sinemurian.
In the geologic timescale, the Sinemurian is an age and stage in the Early or Lower Jurassic Epoch or Series. It spans the time between 199.5 ±0.3 Ma and 192.9 ±0.3 Ma. The Sinemurian is preceded by the Hettangian and is followed by the Pliensbachian.
The Oxfordian is, in the ICS' geologic timescale, the earliest age of the Late Jurassic Epoch, or the lowest stage of the Upper Jurassic Series. It spans the time between 161.5 ± 1.0 Ma and 154.8 ± 0.8 Ma. The Oxfordian is preceded by the Callovian and is followed by the Kimmeridgian.
Arctoptychites is a genus of extinct cephalopods belonging to the ceratitid family Ptychitidae, and related to such genera as Ptychites and Aristoptychites; all from the Triassic.
Ussuria is a genus of Lower Triassic ammonites with a smooth, involute discoidal shell with submonophyllic sutures, belonging to the ceratitid family Ussuriidae.
Ceratitida is an order that contains almost all ammonoid cephalopod genera from the Triassic as well as ancestral forms from the Upper Permian, the exception being the phylloceratids which gave rise to the great diversity of post-Triassic ammonites.
Desmoceratidae is a family belonging to the ammonite superfamily Desmoceratoidea. They are an extinct group of ammonoids, shelled cephalopods related to squid, belemnites, octopuses, and cuttlefish, and more distantly to the nautiloids, that lived between the Lower Cretaceous and Upper Cretaceous.
Ptychitoidea, formerly Ptychitacheae, is a superfamily of typically involute, subglobular to discoidal Ceratitida in which the shell is smooth with lateral folds or striations, inner whorls are globose, and the suture is commonly ammonitic. Their range is Middle_ and Upper Triassic.
Sturia is a genus of ceratitid ammonoids from the Lower Triassic with an ammonitic suture.
