Abstract: 

Brachiopods from the Dinarides of the NE Herzegovina are described for the first time in the present paper. The following species have been recorded: Nucleata ex gr. aspasia (Meneghini), Lobothyris punctata (J. Sowerby) – from the Pliensbachian micritic limestones; Pseudogibbrirhynchia moorei (Davidson), P. jurensis (Quenstedt), Stolmorhynchia bouchardi (Quenstedt), Cuersithyris provincialis (Deslongchamps) – from the Lower Toarcian rocks; Somalirhynchia velezensis sp. n. – from the Upper Oxfordian-Lower Kimmeridgian peri-reefal limestones. The Lower Jurassic species are being more often described from the Mediterranean brachiopod province, but their distribution is controlled rather by ecological factors – a long shelf sublittoral biotope with carbonate sedimentation distant from the beach, with low input of detrital material, than by climatic and physical factors. The Upper Jurassic Somalirhynchia velezensis sp. n. occurs in peri-reefal biotope.

М. Гакович, П. Чумаченко. Юрские брахиоподы из Динаридов (СВ Герцеговина). Впервые описаны юрские брахиоподы из Динаридов Северо-Восточной Герцеговины. Из плинсбахских известняков описаны Nucleata ex gr. aspasia (Meneghini), Lobothyris punctata (J. Sowerby); из тоарских седиментов – Pseudogibbrirhynchia moorei (Davidson), P. jurensis (Quenstedt), Stolmorhynchia bouchardi (Quenstedt), Cuersithyris provincialis (Deslongchamps) и из верхнеоксфордских-нижнекимеридижских пери-рифовых известняков – Somalirhynchia velezensis sp. n. Нижнеюрскиетаксоны чаще всего относятся к Медитеранской брахиоподовой провинции, но вероятно на их распространение прежде всего влияют экологические факторы – сублиторальный шельфовы биотоп с карбонатной седиментацией, расположенный далеко от побережья, со слабым привносом детритового материала, чем климатические факторы и физические барьеры. Верхнеюрская Somalirhynchia velezensis sp. n., найденная в пери-рифовом биотопе.
