Dromopus - это рептилий Ichnogenus, который обычно встречается в объединениях ихнофоссилах , датируемых покойным Пенсильванским ( Москосковийская сцена), до поздней пермской ( Чангсинскую сцену). Он был найден по всей Европе, а также в Соединенных Штатах, Канаде и Марокко. Было названо несколько iChnospecies; Только тип ichnospecies D. lacertoides окончательно признается. [ 1 ]
История
[ редактировать ]Разновидность
[ редактировать ]инопейзии саурихнитов как названные Первоначально названный в 1861 году, , S. lacertoides был перенесен в недавно созданный род Dromopus Отнелом Чарльзом Маршем в 1894 году вместе с новыми иноспективами D. Agilis из Соединенных Штатов. [ 2 ]
В 1929 году Рой Муди описал двухзначные следы из красных слоев Техаса под Ichnospecies Varanopus Palmatus , V. Impressus , V. Elrodi и V. Didactylus . [ 3 ] Тем не менее, впоследствии считалось, что они представляют собой единую их анопейность Дромопуса Уильямом Сарджантом . Поскольку образца тип V. palmatus сломлен, а V. Impressus и V. elrodi неполны, Dromopus didactylus, как правило, является предпочтительным названием. [2]
In 1963 and 1964, Paul Ellenberger described many ichnospecies of Dromopus: D. neooctavianensis, D. brevidigitatus, D. duidigitatus, D. octavianensis, D. bidigitatus, D. curtidigitus, D. inversidigitulifer, D. rabejacensis, D. rectidigitus, D. rectangulus, D. exsultans, and D. cursor. Harmut Haubold considered them invalid in a 2000 review.[4]
There have been disagreements about whether the North American D. agilis represents a separate ichnospecies.[5] More recently, based on the fact that there is no satisfactory anatomical diagnosis distinguishing various ichnospecies of Dromopus, only the type ichnospecies D. lacertoides has been agreed to be valid.[1][6]
Synonyms
[edit]In 1892, Pohlig used the new ichnogenus Protritonichnites for the ichnospecies Saurichnites lacertoides, before Marsh had named Dromopus. By the principles of synonymy, Protritonichnites should have priority over Dromopus. However, in 1970, Haubold argued that this name was largely unused by this point, and it was also based on a less taxonomically sound definition. Although some European researchers during the 1980s persisted in using the name Protritonichnites, Dromopus has generally found more widespread adoption.[5] Other synonyms include Eumekichnium, named by Franz Nopcsa in 1923, including the type ichnospecies E. longipollex, as well as E. gampsodactylum and E. pachydactylum (both formerly Ichnium); and Gampsodactylum, also named by Nopcsa in 1923, including the type ichnospecies G. alberdorfense as well as G. friedrichrodanum and G. kabarzense.[4]
Description
[edit]Dromopus lacertoides tracks are characterized by five-fingered hand and foot imprints up to 6 centimetres (2.4 in) long, about a third longer than they are wide, with a short palm and long, slender, tapered digits. The length of the digits increases from the first to the fourth, with the fifth having the same length as the second. The hand and foot imprints are not particularly distinct.[7] D. didactylus tracks are based on similar tracks, but where the imprints of all but two digits are faint.[2]
Dromopus tracks have been ascribed to lizard-like reptiles, including the diapsid Araeoscelidia and the parareptilian Bolosauridae.[1][8][9]
