Gaetano Giorgio Gemmellaro
Gaetano Giorgio Gemmellaro (24 February 1832, in Catania – 16 March 1904, in Palermo) was an Italian geologist, paleontologist and politician. Biography Gemmellaro was the son of Carlo Gemmellaro, a teacher of geology at the University of Catania. He studied medicine, specialising in ophthalmology at the University of Naples Federico II. Here he met Arcangelo Scacchi, who introduced him to natural sciences, specifically geology and mineralogy, disciplines in which Gemmellaro published a series of memoirs. In 1858, he was appointed special professor of geology and mineralogy at the University of Catania. During this time, he met the English geologist Charles Lyell, who employed Gemmellaro to study the stratigraphy of the Etna lava, in exchange for two publications in the annals of the Geological Society of London. In 1860, he was commissioned by the British Government to conduct geological surveys of the Canary Islands. During the trip, however, learning of Giuseppe Garibald ...

Agathiceratidae
Agathiceratidae, as revised, makes up the goniatitid superfamily Agathiceratoidea. Agathiceratidae, which lived from the Upper Carboniferous (Pennsylvanian) to the Middle Permian, combine related genera with subdiscoidal to globular shells that have a small umbilicus and goniatitic sutures and are prominently longitudinally lirate. (Miller ''et al.'' 1960) The explanation for the Agathiceratidae is that for the Agathiceratoidea. Agathiceratidae may have its origin in ''Dombarites'' (Saunders ''et al.'' 1999) which has been removed to the Delepinoceratidae (Furnish ''et al.'' 2009). Delepinoceratidae is now one of two families that make up the Goniatitoidea. In current taxonomy (Furnish ''et al.'' 2009), Agathiceratidae contains '' Agathiceras'', '' Gaetanoceras'', '' Paragathiceras'', and '' Pericleites'' as compared to ''Dombarites'', '' Paracravenoceras'', ''Periclietes'', '' Proshumardites'', and ''Agathiceras'' in Saunders ''et al.'' (1999). ''Paracravenoceras'' is now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
