Pallimnarchus Lectotype
''Paludirex'' (meaning "swamp king") is an extinct genus of mekosuchine crocodylian from the Pliocene and Pleistocene of Australia. A large and robust semi-aquatic ambush hunter capable of attaining lengths of up to , it was likely the top predator of Australia's waterways prior to the appearance of modern saltwater crocodiles. Two species are known, the smaller ''Paludirex gracilis'' and the larger ''Paludirex vincenti''. A third as of yet unnamed species may have also existed. The history of ''Paludirex'' is long and complicated, largely due to its connection with the historic genus ''Pallimnarchus''. While the name ''Pallimnarchus'' was coined in 1886, making it the first fossil crocodile named from Australia, this was done so merely out of convenience, and this initial description did not come with a proper diagnosis. Despite the lacking definition, subsequent authors referred more and more material to this genus, leading to several attempts at redefining it during the late 20 ...

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Apatite
Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of Hydroxide, OH−, Fluoride, F− and Chloride, Cl− ion, respectively, in the crystal. The formula of the admixture of the three most common Endmember (mineralogy), endmembers is written as Calcium, Ca10(Phosphate, PO4)6(OH,F,Cl)2, and the crystal unit cell formulae of the individual minerals are written as Ca10(PO4)6(OH)2, Ca10(PO4)6F2 and Ca10(PO4)6Cl2. The mineral was named apatite by the German geologist Abraham Gottlob Werner in 1786, although the specific mineral he had described was reclassified as fluorapatite in 1860 by the German mineralogist Karl Friedrich August Rammelsberg. Apatite is often mistaken for other minerals. This tendency is reflected in the mineral's name, which is derived from the Greek word ἀπατάω (apatáō), which means ''to deceive''. Geology Apatite is very common as an accessory mineral in igneous and metamorphic roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paul Willis (science Communicator)
Paul M. A. Willis is an Australian Palaeontology, palaeontologist, Science communication, science communicator and former Director of the Royal Institution of Australia (RiAus). Career Willis studied zoology and geology at University of Sydney and went on to complete a PhD in palaeontology at the University of New South Wales. He has been a resident palaeontologist on ten Antarctic expeditions and has written or co-authored eight books on dinosaurs, rocks and fossils. While Willis found his first fossil when he was six, the earliest part of his collection was a small echinoid collected by his parents on their honeymoon. Willis completed a BSc at Sydney University in zoology and geology before conducting a PhD at the University of New South Wales. His Doctoral thesis was on The Phylogenetic Systematics of Australasian Crocodilians. Willis's doctoral studies resulted in the erection of several new taxa including the subfamily Mekosuchinae, and the genera ''Baru'', ''Kambara,'' '' ...

Mekosuchinae
Mekosuchinae is an extinct clade of crocodilians from the Cenozoic of Australasia. They represented the dominant group of crocodilians in the region during most of the Cenozoic, first appearing in the fossil record in the Eocene of Australia, and surviving until the arrival of humans: the Late Pleistocene on the Australian continent and during the Holocene in the Pacific islands of Fiji, New Caledonia and Vanuatu. Mekosuchine crocodiles are a diverse group displaying a great variety of shapes and sizes. Some taxa, like ''Baru'' and ''Paludirex'', were large semi-aquatic ambush hunters, though the two genera likely differed significantly in their hunting methods. The medium-sized ''Australosuchus'' may have been relatively cold-resistant and taxa like ''Trilophosuchus'' and ''Mekosuchus'' are renowned for their small size. One of the most distinct mekosuchines was ''Quinkana'', with its altirostral (deep) skull and blade-like serrated teeth. There is some question around the lifest ...

New Guinea Crocodile
The New Guinea crocodile (''Crocodylus novaeguineae'') is a small species of crocodile found on the island of New Guinea north of the mountain ridge that runs along the centre of the island. The population found south of the mountain ridge, formerly considered a genetically distinct population, is now considered a distinct species, Hall's New Guinea crocodile (''C. halli''). In the past it included the Philippine crocodile, ''C. n. mindorensis'', as a subspecies, but today they are regarded as separate species. The habitat of the New Guinea crocodile is mostly freshwater swamps and lakes. It is most active at night when it feeds on fish and a range of other small animals. A female crocodile lays a clutch of eggs in a nest composed of vegetation and she lies up nearby to guard the nest. There is some degree of parental care for newly hatched juveniles. This crocodile was over-hunted for its valuable skin in the mid 20th century, but conservation measures have since been put in pla ...

Lectotype
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is a ...
