Gooloogongia
''Gooloogongia'' ( ) is a genus of prehistoric lobe-finned fish which belonged to the group of rhizodont fishes. ''Gooloogongia'' lived during the Late Devonian period (Famennian stage, about 360 million years ago). Fossils have been found in the Canowindra site, ( Australia). It was named by Zerina Johanson and Per Ahlberg in 1998. In general size and shape ''Gooloogongia'' is similar to the modern saratoga which lives in the tropical rivers of northern Australia. ''Gooloogongia loomesi'' ("Loomes' Gooloogong") named after Bruce Loomes, the foreman of the 1993 excavation of the Canowindra site, and the town of Gooloogong, NSW. Description ''Gooloogongia'' was large in size (about 90 cm). Like other lobe-finned fishes, ''Gooloogongia'' had two rows of teeth in the jaw, the outer row being small teeth, and the inner row being larger fangs. The fangs of ''Gooloogongia'' are sharp and needle-like, but they were probably not strong enough to penetrate the armor plating of s ...

Rhizodonts lived in tropical rivers and freshwater lakes and were the dominant predators of their age. They reached huge sizes - the largest known species, '' Rhizodus hibberti'' from Europe and North America, was an estimated 7 m in length, making it the largest freshwater fish known. Description The upper jaw had a marginal row of small teeth on the maxilla and premaxilla, medium-sized fangs on the ectopterygoid and dermopalatine bones, and large tusks on the vomers and premaxillae.

Late Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Saratoga (fish)
The southern saratoga (''Scleropages leichardti''), also known as the spotted bonytongue, spotted saratoga, or simply saratoga, is a freshwater bony fish native to Australia. It belongs to the subfamily Osteoglossinae, or arowanas, a primitive group of teleosts. Like all arowanas, it is a carnivorous mouthbrooder. Along with the gulf saratoga (''Scleropages jardinii''), the saratoga is also known as the Australian arowana (mainly by non-Australian aquarists) and barramundi, although the latter name is nowadays reserved in Australia for the unrelated ''Lates calcarifer''. This species is found in turbid waters and has a more restricted distribution than the other ''Scleropages'' native to Australia, ''Scleropages jardinii''. Description Southern saratoga can grow up to . At sexual maturity, they are usually in length. They are primitive, surface-dwelling fish with strongly compressed bodies. They have an almost perfectly flat back, with a dorsal fin set back towards the tail of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Placodermi
Placodermi (from Greek πλάξ 'plate' and δέρμα 'skin', literally ' plate-skinned') is a class of armoured prehistoric fish, known from fossils, which lived from the Silurian to the end of the Devonian period. Their head and thorax were covered by articulated armoured plates and the rest of the body was scaled or naked, depending on the species. Placoderms were among the first jawed fish; their jaws likely evolved from the first of their gill arches. Placoderms are thought to be paraphyletic, consisting of several distinct outgroups or sister taxa to all living jawed vertebrates, which originated among their ranks. In contrast, one 2016 analysis concluded that placodermi are likely monophyletic, though these analyses have been further dismissed with more transitional taxa between placoderms and modern gnathosthomes, solidifying their paraphyletic status. Placoderms were also the first fish to develop pelvic fins, the precursor to hindlimbs in tetrapods, as well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Million Years Ago
The abbreviation Myr, "million years", is a unit of a quantity of (i.e. ) years, or 31.556926 teraseconds. Usage Myr (million years) is in common use in fields such as Earth science and cosmology. Myr is also used with Mya (million years ago). Together they make a reference system, one to a quantity, the other to a particular place in a year numbering system that is ''time before the present''. Myr is deprecated in geology, but in astronomy ''Myr'' is standard. Where "myr" ''is'' seen in geology it is usually "Myr" (a unit of mega-years). In astronomy it is usually "Myr" (Million years). Debate In geology a debate remains open concerning the use of ''Myr'' (duration) plus ''Ma'' (million years ago) versus using only the term ''Ma''. In either case the term '' Ma'' is used in geology literature conforming to ISO 31-1 (now ISO 80000-3) and NIST 811 recommended practices. Traditional style geology literature is written The "ago" is implied, so that any such year number "X M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
