Eber Bunker
Eber Bunker (1761–1836) was a sea captain and pastoralist, and he was born on 7 March 1761 at Plymouth, Massachusetts. He commanded one of the first vessels to go whaling and sealing off the coast of Australia. His parents were James Bunker and his wife Hannah, née Shurtleff. 1776-1786: Background When England lost its American colonies in 1776 in the American Revolutionary War, it lost an important source of raw materials as well as its established dumping grounds for convicted criminals. Consequently, England saw an urgent need to replace these critical resources. Despite the enormous expenses associated with starting a new colony on a virtually uncharted continent in another hemisphere, England elected to establish a penal colony at Botany Bay under the leadership of Captain Arthur Phillip. This project was undertaken in part to relieve overcrowding in the English prisons, as well as to establish a new source for timber and other raw materials, and also to establish a deep ...

Schooner
A schooner () is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast. A common variant, the topsail schooner also has a square topsail on the foremast, to which may be added a topgallant. Differing definitions leave uncertain whether the addition of a fore course would make such a vessel a brigantine. Many schooners are gaff-rigged, but other examples include Bermuda rig and the staysail schooner. The origins of schooner rigged vessels is obscure, but there is good evidence of them from the early 17th century in paintings by Dutch marine artists. The name "schooner" first appeared in eastern North America in the early 1700s. The name may be related to a Scots word meaning to skip over water, or to skip stones. The schooner rig was used in vessels with a wide range of purposes. On a fast hull, good ability to windward was useful for pri ...

Gastrochaenolites
''Gastrochaenolites'' is a trace fossil formed as a clavate (club-shaped) boring in a hard substrate such as a shell, rock or carbonate hardground. The aperture of the boring is narrower than the main chamber and may be circular, oval, or dumb-bell shaped (Kelly and Bromley, 1984). ''Gastrochaenolites'' is most commonly attributed to bioeroding bivalves such as '' Lithophaga'' and ''Gastrochaena'' (Kleeman, 1980). The fossil ranges from the Ordovician The Ordovician ( ) is a geologic period and system, the second of six periods of the Paleozoic Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. ... to the Recent (Taylor and Wilson, 2003; Vinn and Wilson, 2010).

Ichnogenus
An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. ''Ichnotaxa'' comes from the Greek ίχνος, ''ichnos'' meaning ''track'' and ταξις, ''taxis'' meaning ''ordering''.Definition o'ichno'at dictionary.com. Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils. They are assigned genus and species ranks by ichnologists, much like organisms in Linnaean taxonomy. These are known as ichnogenera and ichnospecies, respectively. "Ichnogenus" and "ichnospecies" are commonly abbreviated as "igen." and "isp.". The binomial names of ichnospecies and their genera are to be written in italics. Most researchers classify trace fossils only as far as the ichnogenus rank, based upon trace fossils that resemble each other in morphology but have subtle differences. Some authors have constructed detailed hierarchies up to ichnosu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodolith
Rhodoliths (from Greek for ''red rocks'') are colorful, unattached calcareous nodules, composed of crustose, benthic marine red algae that resemble coral. Rhodolith beds create biogenic habitat for diverse benthic communities. The rhodolithic growth habit has been attained by a number of unrelated coralline red algae, organisms that deposit calcium carbonate within their cell walls to form hard structures or nodules that resemble beds of coral. Rhodoliths do not attach themselves to the rocky seabed. Rather, they roll like tumbleweeds along the seafloor until they become too large in size to be mobilised by the prevailing wave and current regime. They may then become incorporated into a semi-continuous algal mat or form an algal build-up. While corals are animals that are both autotrophic (photosynthesize via their symbionts) or heterotrophic (feeding on plankton), rhodoliths produce energy solely through photosynthesis (i.e. they can only grow and survive in the photic zone ...

Brown Booby
The brown booby (''Sula leucogaster'') is a large seabird of the booby family Sulidae, of which it is perhaps the most common and widespread species. It has a pantropical range, which overlaps with that of other booby species. The gregarious brown booby commutes and forages at low height over inshore waters. Flocks plunge-dive to take small fish, especially when these are driven near the surface by their predators. They only nest on the ground, and roost on solid objects rather than the water surface. Taxonomy The brown booby was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his ''Histoire Naturelle des Oiseaux'' in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'' which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Buffon did not include a scientific name with his description but in 1783 the Dutch natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capricorn Silvereye
The Capricorn silvereye (''Zosterops lateralis chlorocephalus''), also known as the Capricorn white-eye or green-headed white-eye, is a small greenish bird in the Zosteropidae or white-eye family. It is a subspecies of the silvereye that occurs on islands off the coast of Queensland in north-eastern Australia, and which is sometimes considered to be a full species. Description The Capricorn silvereye is the only bird endemic to the Great Barrier Reef. It was first described by Archibald Campbell and Samuel White in '' The Emu'' from specimens collected during an expedition by the Royal Australasian Ornithologists Union to the Capricorn Group in October 1910. They wrote: ''Zosterops'' were numerous, and appeared to breed on the islands, judging by a few old nests. As at some of our more southern camps, it was delightful to listen to the subdued chorus of the birds' sweet warbling songs at daybreak. Regularly on Masthead they commenced to warble from 10 to 5 minutes befor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
