Cheirothricidae - Exocoetoides Minor
Cheirothricidae is a family of extinct marine Actinopterygii, ray-finned fish, perhaps belonging to the Aulopiformes, although they are tentatively placed as indeterminate Eurypterygii, eurypterygians. They lived during the Upper Cretaceous (Cenomanian - Campanian, about 95 - 71 million years ago) and their fossil remains are found in the Middle East and Europe. They were characterized by very expanded even fins. Genera *†''Cheirothrix'' Pictet and Humbert, 1866 - Late Santonian to Campanian of Germany and Lebanon *†''Exocoetoides'' Davis, 1887 - Late Cenomanian of Lebanon *?†''Telepholis'' von der Marck, 1868 - Late Campanian of Germany (possibly a stem-Stomiiformes, stomiiform) Description The main characteristic of these small fish (the length of the body was usually between 3 and 20 centimeters in length) was given by the extreme development of the even fins; in ''Cheirothrix'' species the pectoral fins were particularly developed, while in ''Telepholis'' and ''Exocoeto ...

Exocoetoides
''Exocoetoides'' is an extinct genus of prehistoric ray-finned fish. Etymology The Latin genus name is derived from its resemblance to '' Exocoetus'', a modern-day flying fish. Description ''Exocoetoides'' species could reach a body length of about . The main characteristic of these decidedly small fishes was given by the extreme development of the even fins. In particular, the pectoral fins were particularly long (they could reach the anal region). Also the pelvic fins were large. Moreover the fins were provided with very long rays. In the caudal fin both lobes were the same size. Like today's modern-day flying fish they were also likely to perform a sort of gliding flight over water, thanks to the notable expansion of the pectoral and pelvic fins.[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
