“…Khalloufi and Jalil (2020) described a Carnian ichthyofauna from a locality very close (hundreds of meters) to the coprolite locality. This ichthyofauna is composed mainly of actinopterygians ( Dipteronotus gibbosus , cf.…”

“…The lack of spiral morphology, characteristic of some fish, and the large size suggest that the non-spiral coprolites could have been produced by tetrapods (Qvarnström 2020), The base of the T5 member (in the same study zone) yielded a tetrapod fauna that includes metoposaurids, almasaurids, dicynodonts, phytosaurs, and rauisuchians. These tetrapods could be potential producers of the large-sized non-spiral coprolites studied herein (e.g., Dutuit 1976Dutuit , 1979Jalil 1999;Khalloufi and Jalil 2020).…”

“…The Argana Basin occupies an important place in Triassic non-marine paleontology. It is known to produce one of the most important Triassic fossil records of a diverse continental vertebrate fauna and ichnofauna (Dutuit 1976(Dutuit , 1979Jalil 1999;Klein et al 2009Klein et al , 2011Lagnaoui et al 2012Lagnaoui et al , 2016Khalloufi and Jalil 2020;Zouheir et al 2020). The Basin is located in an important position in Pangea in the present day Western High Atlas of Morocco (Fig.…”

A large collection of vertebrate coprolites derives from a debris flow conglomerate in the Upper Triassic Irohalene Member (Carnian) of the Timezgadiouine Formation, northern Argana Basin, Morocco. The coprolites are classified into 14 different morphotypes (MA to MN) based on their size, shape, and surface texture that are divided into three groups: striated coprolites; spiral and scroll-like coprolites; and non-spiral coprolites lacking striations. The great variety of morphotypes suggests the coprolites correspond to a variety of terrestrial and aquatic carnivorous producers. The carnivore coprolites lithified rapidly and were deposited in a high-energy sheetflood. The majority of the coprolites were produced by semi-aquatic and terrestrial tetrapods, with a small percentage produced by fish. The occurrence of Dicynodontocopros, common Alococopros, and some heteropolar forms with affinities to Heteropolacopros, are consistent with a late Carnian age for the Irohalene Member. The Irohalene coprolites are mostly similar to those of the coprofaunas of late Carnian age (Otischalkian–Adamanian) in the lower Chinle Group of the western United States in the co-occurrence of Alococopros and Dicynodontocopros. Significantly, this Moroccan coprofauna from Gondwana has close Laurussian relationships.
