Armigatus
''Armigatus'' is an extinct genus of clupeomorph fishes belonging to the order Ellimmichthyiformes. These fishes lived in the Cretaceous (Albian to Turonian, about 103-90 million years ago); their fossil remains have been found in Mexico, Croatia, the Middle East and North Africa, suggesting the genus ranged across the Tethys Sea. Etymology The Latin genus name ''armigatus'', means ''bearer of armor''. ''Brevissimus'' signifies "shortest, smallest". Description ''Armigatus'' has an osteoglossid-like tooth patch, a large foramen in the anterior ceratohyal and a series of subtriangular dorsal scutes, giving rise to their scientific name.

Sannine Formation
The Sannine Formation, also called the Sannine Limestone, is a Cretaceous geologic formation in Lebanon. Description It is primarily Cenomanian in age. The formation laterally varies from east to west; the western lowland "coastal" sequence is over 2000 metres thick and primarily consists of deep water limestone and chalk, while the eastern "mountain" sequence is 500–700 metres thick and consists of shallow water limestone. Pterosaur fossils have been recovered from the formation, including those of ''Mimodactylus'' and ''Microtuban''. The pythonomorphs '' Pontosaurus, Eupodophis'' and probably '' Aphanizocnemus'' are known from the formation. Insects are also known from compression fossils, including those of a dragonfly, enigmatic pond-skater like insect '' Chresmoda.'' and a mesoblattinid cockroach.P. Vršanský and E.

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Scute
A scute or scutum (Latin: ''scutum''; plural: ''scuta'' "shield") is a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians, and the feet of birds. The term is also used to describe the anterior portion of the mesonotum in insects as well as some arachnids (e.g., the family Ixodidae, the scale ticks). Properties Scutes are similar to scales and serve the same function. Unlike the scales of lizards and snakes, which are formed from the epidermis, scutes are formed in the lower vascular layer of the skin and the epidermal element is only the top surface . Forming in the living dermis, the scutes produce a horny outer layer that is superficially similar to that of scales. Scutes will usually not overlap as snake scales (but see the pangolin). The outer keratin layer is shed piecemeal, and not in one continuous layer of skin as seen in snakes or lizards. The dermal base may contain bone and produce dermal armour. Scutes with a bony ...

Clupeiformes
Clupeiformes is the order of Actinopterygii, ray-finned fish that includes the herring family, Clupeidae, and the anchovy family, Engraulidae. The group includes many of the most important Forage fish, forage and food fish. Clupeiformes are physostomes, which means that their gas bladder has a pneumatic duct connecting it to the Gut (zoology), gut. They typically lack a lateral line, but still have the eyes, Fish fin, fins and Fish scale, scales that are common to most fish, though not all fish have these attributes. They are generally silvery fish with streamlined, spindle-shaped, bodies, and they often Shoaling and schooling, school. Most species eat plankton which they filter from the water with their gill rakers. The former order of Isospondyli was subsumed mostly by Clupeiformes, but some isospondylous fishes (isospondyls) were assigned to Osteoglossiformes, Salmoniformes, Cetomimiformes, etc. Families The order includes about 405 species in seven families: * Order Clup ...

Dalmatia
Dalmatia (; hr, Dalmacija ; it, Dalmazia; see #Name, names in other languages) is one of the four historical region, historical regions of Croatia, alongside Croatia proper, Slavonia, and Istria. Dalmatia is a narrow belt of the east shore of the Adriatic Sea, stretching from the island of Rab in the north to the Bay of Kotor in the south. The Dalmatian Hinterland ranges in width from fifty kilometres in the north, to just a few kilometres in the south; it is mostly covered by the rugged Dinaric Alps.

Campanian
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 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian. The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks. Etymology The Campanian was introduced in scientific literature by Henri Coquand in 1857. It is named after the French village of Champagne in the department of Charente-Maritime. The original type locality was a series of outcrop near the village of Aubeterre-sur-Dronne in the same region.

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...

Hjoula
Hjoula ( ar, حجولا) is a municipality in the Byblos District of Keserwan-Jbeil Governorate, Lebanon. It is 70 kilometers north of Beirut. Hjoula has an elevation of between 920 and 1,100 meters above sea level. Hjoula has a total land area of 528 hectares. The village of Hjoula is known for its fertile soil and its woods, as well as Early Cretaceous fossils. Etymology The word is an Aramaic one, however the meaning is uncertain. Most historians and linguists suggest it means "Oval" due to its oval shape, while some others speculate it comes from the Syriac root "G-l-a" and subsequently to the word "Guola" which supposedly means "The place of the wandering salesman". History Many old relics and monuments were found in Hjoula. There was found a Phoenician inscription in "Jarabta". A Roman statue that represented a shepherd and his sheep was also found beside the lake, and was dated to the era of emperor Tiberius c. 20 CE; along small sets of coins that were written in Kufic wi ...
