Aipichthys is an extinct genus of bony fish that is possibly polyphyletic. [1] Formerly classified in the Polymixiiformes, it is now thought to be a distant relative of oarfish and opahs. [2] [3]
Five species have traditionally placed within Aipichthys, but a redescription of the type species in 2016 suggested the genus to be polyphyletic, with only the type species as a member of the genus. The other four species were not moved out of the genus by the authors and were referred as `Aipichthys`.
Lampriformes is an order of ray-finned fish. Members are collectively called lamprids or lampriforms, and unite such open-ocean and partially deep-sea Teleostei as the crestfishes, oarfish, opahs, and ribbonfishes. A synonym for this order is Allotriognathi, while an often-seen, but apparently incorrect, spelling variant is Lampridiformes. They contain seven extant families which are generally small but highly distinct, and a mere 12 lampriform genera with some 20 species altogether are recognized. They are the only extant members of the superorder Lamprimorpha, which was formerly diverse throughout much of the Late Cretaceous.
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly. It is contrasted with monophyly and paraphyly.
Tachypleus is a genus of south, southeast and east Asian horseshoe crabs in the family Limulidae.
Acanthomorpha is an extraordinarily diverse taxon of teleost fishes with spiny fin rays. The clade contains about one-third of the world's modern species of vertebrates: over 14,000 species.
Amphistium paradoxum, the only species classified under the genus Amphistium and the family Amphistiidae, is a fossil fish which has been identified as a Paleogene relative of the flatfish, and as a transitional fossil. In a typical modern flatfish, the head is asymmetric with both eyes on one side of the head. In Amphistium, the transition from the typical symmetric head of a vertebrate is incomplete, with one eye placed near the top of the head.
Bajaichthys is an extinct Ypresian zeid from the Monte Bolca Lagerstätten of Italy. It contains a single species, B. elegans, and is the only member of the family Bajaichthyidae.
Protozeus kuehnei is an extinct species of fish from the Ypresian epoch Fur Formation of Denmark.
Archaeozeus is an extinct genus of marine ray-finned fish from the Ypresian epoch Fur Formation of Denmark. It contains a single species, A. skamolensis, and is the only member of the family Archaeozeidae. It is considered the most basal member of the order Zeiformes.
Aipichthyoides is an extinct genus of prehistoric marine bony fish that lived during the lower Cenomanian in what is now the West Bank. Formerly classified in the Polymixiiformes, it is now thought to be a distant relative of oarfish and opahs.
Styletoctopus is an extinct genus of octopus. The genus consists of the single species Styletoctopus annae, which lived approximately 95 million years ago during the late Cenomanian,. It was first discovered in 2009 by a team led by Dirk Fuchs of Freie University in the Hâqel and Hjoula localities in Lebanon. Very few octopus species appear in the fossil record, as octopuses consist of soft tissue that usually decomposes before it has time to fossilize.
Keuppia is an extinct genus of octopus.
The paleontological sites of Lebanon contain deposits of well preserved fossils and include some species found nowhere else. Notable among these is the Lebanese lagerstätten of the Late Cretaceous age, which contain a well-preserved variety of different fossils. Some fossils date back to the Jurassic period, and younger fossils of mammals from a different site belong to the Miocene through the Pleistocene.
Microtuban is an extinct genus of azhdarchoid pterosaur known from the Late Cretaceous of northern Lebanon.
Sthenopis pretiosus, the gold-spotted ghost moth, is a species of moth of the family Hepialidae. It was first described by Gottlieb August Wilhelm Herrich-Schäffer in 1856. It can be found in found Brazil, Venezuela and in the eastern United States and south-eastern Canada.
Lobophylliidae is a family of large polyp stony corals. The family was created in 2009 after a revision of the "robust" families of Faviidae, Merulinidae, Mussidae and Pectiniidae, which had been shown to be polyphyletic. The family Lobophylliidae was formed out of the Indo-Pacific species that had traditionally been included in Mussidae, and some of the species which had previously formed Pectiniidae, the remaining species from Pectiniidae having been merged into Merulinidae. The type genus is Lobophyllia.
Hjoula is a municipality in the Byblos District of Keserwan-Jbeil Governorate, Lebanon. It is 70 kilometres (43 mi) north of Beirut. Hjoula has an elevation of between 920 and 1,100 metres 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.
Armigatus is an extinct genus of marine clupeomorph fishes belonging to the order Ellimmichthyiformes. These fishes lived in the Cretaceous ; their fossil remains have been found in Mexico, Croatia, the Middle East and North Africa, suggesting the genus ranged across the Tethys Sea.
Mimodactylus is a genus of istiodactyliform pterosaur that lived in what is now Lebanon during the Late Cretaceous, 95 million years ago. The only known specimen was discovered in a limestone quarry near the town of Hjoula, belonging to the Sannine Formation. The owner of the quarry allowed the specimen to be prepared and scientifically described by an international team of researchers, and when it was eventually sold, the buyer donated it to the MIM Museum in Beirut. In 2019, the researchers named the new genus and species Mimodactylus libanensis; the generic name refers to the MIM Museum, combined with the Greek word daktylos for "digit", and the specific name refers to Lebanon. The well-preserved holotype specimen is the first complete pterosaur from the Afro-Arabian continent, and the third pterosaur fossil known from Lebanon.
Sculda is an extinct genus of mantis shrimp known from the late Jurassic to late Cretaceous of Germany and Lebanon. Although several species have been assigned to it, some are now deemed dubious or moved to different genera. It was a moderate-sized crustacean, measuring no more than 50 mm (2.0 in) long. Sculda would have lived in a marine environment and been a predatory animal, likely smashing its prey with the widened segment of its raptorial appendages before cutting it with the sharp appendage tips.
Lamprimorpha is a superorder of marine ray-finned fishes, representing a basal group of the highly diverse clade Acanthomorpha. Represented today only by the order Lampriformes, recent studies have recovered other basal fossil species of the group dating as far back as the Cenomanian stage of the Late Cretaceous. Some of these fossil taxa, such as the paraphyletic genus Aipichthys, are among the oldest known fossil acanthomorphs, and overall they appear to have been a major component of the marine fish fauna at that time. Lamprimorpha is thought to be the sister group to the superorder Paracanthopterygii, which contains cod, dories, and trout-perches.
