Percalatoidei
''Percalates'' (from '' Perca'' + ''Lates'') is a genus of ray-finned fish native to both estuarine and freshwater habitats of southeastern Australia. They are the only members of the suborder Percalatoidei, and of their own undescribed family ('Percalatidae'). Description It contains two species, both of which were previously placed in the temperate perch genus ''Macquaria''. However, more recent phylogenetic studies have found these two species to be the most basal members of the order Centrarchiformes, and thus more distantly related to the temperate perches than previously thought. The following species are known: * '' Percalates colonorum'' ( Günther, 1863) - estuary perch * ''Percalates novemaculeatus'' (Steindachner, 1866) - Australian bass Well-preserved fossil specimens of the species †'' Percalates antiquus'' Hills, 1934 (=''Macquaria antiquua'') have been recovered from the Early Eocene-aged Redbank Plains Formation of Queensland, Australia.

Centrarchiformes
Centrarchiformes is an order of ray-finned fish, previously included amongst the perciformes. Froese, R. and D. Pauly. Editors. (2023). FishBase. Centrarchiformes. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=1517557 on 2023-11-12 The order Centrarchiformes is not recognized in the 5th Edition (2016) of ''Fishes of the World'', but is accepted on the World Register of Marine Species in November 2023, Fishbase, and ''Eschmeyer's Catalog of Fishes''. Many centrarchiforms look essentially perch-like, featuring a stocky build and a spine-bearing dorsal fin, and range in size from in length (for '' Elassoma gilberti),'' to for the '' Maccullochella peelii.'' The earliest fossils of this group are of '' Percichthys'' from the Early Paleocene of Bolivia, although this status is tentative. If these remains are not of a percichthyid, then the earliest known centrarchiform fossils are of oplegnathids from the Early Eo ...

Estuary Perch
The estuary perch (''Percalates colonorum'') is a species of ray-finned fish endemic to south-eastern Australia, where it prefers brackish waters such as the tidal reaches of coastal lakes, rivers, and streams. Appearance It is very similar to and very closely related to its sister species, the Australian bass, ''Percalates novemaculeata'', differing in having a slightly more "scooped" forehead and reaching a larger length of . The species also differ in that Australian bass generally inhabit freshwater reaches during the non-spawning months, while estuary perch generally inhabit reaches subject to some tidal movement. Most individuals only reach around . The greatest recorded weight for a specimen of this species is , there is very little evidence for this, most people assume it was a typo i.e. it was 10 lb and not 10 kg. Reproduction Estuary perch breed in winter at the same time as Australian bass, and are similarly sexually dimorphic, with females larger than male ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major chang ...

Kuldana Formation
The Kuldana Formation is a fossil-bearing geological formation of Lutetian (Early Eocene) age which outcrop, crops out in northern Pakistan. The abundant fossil remains were deposited by rivers and estuaries crossing an arid to semi-arid environment, between several marine transgressions. Its fossil fauna is best known for the early cetaceans ''Indohyus'', ''Pakicetus'' and ''Ambulocetus'', that helped to shed a new light on the Evolution of cetaceans, evolution of whales, but it also features a large number of early ungulates, rodents and primates. History Fossils from the Kuldana Formation have been studied since long before the name was established, with some of the earliest papers being those of Pilgrim, published in 1940. At that point in time, the sediments were known as the Chharat beds. The name Kuldana Formation as such was first coined by Mir Abdul Latif in 1970, prior to which the sediments had already been known as the Kuldana Beds and Kuldana Series, deriving its n ...

Lutetian
The Lutetian is, in the geologic timescale, a stage (stratigraphy), stage or age (geology), age in the Eocene. It spans the time between . The Lutetian is preceded by the Ypresian and is followed by the Bartonian. Together with the Bartonian it is sometimes referred to as the Middle Eocene Subepoch. Stratigraphic definition The Lutetian was named after Lutetia, the Latin language, Latin name for the city of Paris. The Lutetian Stage was introduced in scientific literature by French geologist Albert de Lapparent in 1883 and revised by A. Blondeau in 1981. The base of the Lutetian Stage is at the first appearance of the nanofossil ''Blackites inflatus'', according to an official reference profile (GSSP) established in 2011. Of two candidates located in Spain, the Gorrondatxe section was chosen.See thwebsite of Eustoquio Molinafor these candidates. The top of the Lutetian (the base of the Bartonian) is at the first appearance of calcareous nannofossils, calcareous nanoplankton s ...

Early Eocene
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene (Early Eocene). Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. The Ypresian is additionally marked by another warming event called the Early Eocene Climatic Optimum (EECO). The EECO is the longest sustained warming event in the Cenozoic record, lasting about 2–3 million years between 53 and 50 Ma. The interval is characterized by low oxygen-18 isotopes, high levels of atmospheric pCO2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edwin Sherbon Hills
Edwin Sherbon Hills (31 August 1906 – 2 May 1986) was an Australian geologist, a Foundation fellow of the Australian Academy of Science and at the time of his death was regarded as one of Australia's "most eminent scientists and most accomplished geologists". first published in Australian Dictionary of Biography, Volume 17, (MUP), 2007. Hills grew in the Melbourne suburb Carlton. He was dux of Carlton Primary School and received a scholarship to attend University High School. Hills graduated from high school in 1924 and with classmate Harrie Massey received a scholarship to attend the University of Melbourne. Hills had chosen his undergraduate courses with the idea of becoming a chemist and took geology as a suitable ancillary, however his studies led him to become a geologist and physiographer. Hills undertook his MSc at the University of Melbourne under E. W. Skeats, his graduate field work was based at Cathedral Range just outside Melbourne and he studied fossil fishes, a ...
