Rhinobatos Sp.
''Rhinobatos'' is a genus of fish in the Rhinobatidae family. Although previously used to encompass all guitarfishes, it was found to be polyphyletic, and recent authorities have transferred many species included in the genus to ''Acroteriobatus'', ''Glaucostegus'', and ''Pseudobatos''. Species The 20 currently recognized species in this genus are: * ''Rhinobatos albomaculatus'' John Roxborough Norman, Norman, 1930 (White-spotted guitarfish) * ''Rhinobatos annandalei'' John Roxborough Norman, Norman, 1926 (Annandale's guitarfish) * ''Rhinobatos austini'' Ebert & Gon, 2017 (Austin’s guitarfish) * ''Rhinobatos borneensis'' Peter Robert Last, Last, Séret & Naylor, 2016 (Borneo guitarfish) * ''Rhinobatos formosensis'' John Roxborough Norman, Norman, 1926 (Taiwan guitarfish) * ''Rhinobatos holcorhynchus'' John Roxborough Norman, Norman, 1922 (Slender guitarfish) * ''Rhinobatos hynnicephalus'' John Richardson (naturalist), J.

Tithonian
In the geological timescale, the Tithonian is the latest age (geology), age of the Late Jurassic Epoch and the uppermost stage (stratigraphy), stage of the Upper Jurassic Series. It spans the time between 149.2 ±0.7 annum, Ma and 143.1 ±0.6 (million years ago). It is preceded by the Kimmeridgian and followed by the Berriasian (part of the Cretaceous). Stratigraphic definitions The Tithonian was introduced in scientific literature by German stratigrapher Albert Oppel in 1865. The name Tithonian is unusual in geological stage names because it is derived from Greek mythology. Tithonus was the son of Laomedon of Troy and fell in love with Eos, the Greek goddess of dawn. His name was chosen by Albert Oppel for this stratigraphy, stratigraphical stage because the Tithonian finds itself hand in hand with the dawn of the Cretaceous. The base of the Tithonian stage is at the base of the ammonite biozone of ''Hybonoticeras, Hybonoticeras hybonotum''. A global reference profile (a GSSP, G ...
