“…11), and is represented in both provinces by P. heimi (Bonet). This species is widely distributed in the Albian-Cenomanian of both Western Tethys and the Gulf Coast (Bonet, 1956;Lucas and Krainer, 2015;Omaña et al, 2019). It has also been recorded from Texas, Florida, and Louisiana in USA (Conkin and Conkin, 1958).…”

The superfamily Alveolinoidea is a member of the Order Miliolida, and is comprised of three main families, the Alveolinidae, the Fabulariidae and the Rhapydioninidae. They are examples of Larger Benthic Foraminifera (LBF), which are single cell organisms with specific characteristic endoskeletons. Alveolinoids are found globally from the Cretaceous to present day and are very important biostratigraphic index fossils in shallow-marine carbonates. They are often associated with significant hydrocarbon reservoirs, and exhibit provincialism with characteristic genera often confined to one of the American, Tethyan or Indo-Pacific provinces. Previously, the systematic study of the global interrelationship between the various alveolinoid lineages has not been possible because of the absence of biostratigraphic correlation between the geographically scattered assemblages, and the scarcity of described material from the Indo-Pacific province. Here we use the literature and new material from the Americas, the French Alps, Iran, Tibet, India and SE Asia, coupled with the use the planktonic foraminiferal zonal (PZ) correlation scheme to put forward, for the very first time, a comprehensive, global, systematic analysis of the biostratigraphic, phylogenetic and palaeogeographic evolution of the alveolinoids. The alveolinoids originated in the Cretaceous in the Tethyan province. During a global sea-level low-stand, a westward migration of some alveolinoids species to the Americas occurred in this period, a behaviour also seen in previous studies of contemporaneous orbitolinid LBF. After the K-P event, which saw the extinction of all Cretaceous alveolinoids, rare new forms of alveolinoids evolved again, first in the Americas and later independently in Tethys. As found in previous studies of rotalid LBF, sea-level low-stands in the Paleocene also allowed some alveolinoid forms to migrate, but this time in an eastward direction from the Americas to Tethys, and from Tethys on to the Indo-Pacific. Alveolinoids still exist today ( Borelis and Alveolinella ), the former of which is cosmopolitan, while the latter is restricted to the Indo-Pacific province. Throughout their phylogenetic history alveolinoids characteristically exhibit convergent evolution, with the repeated re-occurrence of certain morphological features. Understanding this propensity to homoplasy is essential in understanding and constructing the phylogenetic relationships within the alveolinoid superfamily.

“…Further, Hemicyclammina sigali was previously recorded as an Early Albian taxon. In fact, this species was known as an endemic Albian taxon in previous records from Khuzestan and Fars Carbonate Platform (Afghah et al, 2020; Parvaneh Nejad Shirazi et al, 2011; Wynd, 1965), whereas this taxon was also reported from the Cenomanian (Omaña et al, 2019; Vaziri et al, 2005). With regard to the recorded stratigraphic range of the mentioned specimen as an endemic taxon of the Zagros area and both the first appearance datum and last appearance datum of orbitolinids ( Mesorbitolina subconcava and Orbitolina discoidea ) in Fahliyan, logically Mesorbitolina subconcava , Orbitolina discoidea Total Range Zone is approved, which is synchronous with Hemicyclammina sigali , Mesorbitolina subconcava Zone in Interior Fars area (Table 1).…”

“…A previous biostratigraphic study reported that Hemicyclammina sigali was found as common to rare in Albian and Cenomanian strata (Hemleben et al, 1989), while more recent biostratigraphic data confirmed it as a Late Aptian to Early Cenomanian species (Boudagher‐Fadel, 2018). Omaña et al (2019) reported Hemicyclammina sigali from Mid to Upper Cenomanian strata of central‐eastern Mexico which is associated with Pseudolituonella reicheli (Figure 6g), Daxia cenomana , Cuneolina pavonia , Cuneolina parva , and Nezzazata gyra . According to the above‐mentioned studies, Hemicyclammina sigali was found within a Cenomanian faunal assemblage, while our data confirm that it co‐occurs with Albian orbitolinids (e.g., Mesorbitolina texana and Mesorbitolina subconcava ), which agrees with the work of Schroeder et al (2010).…”

A total of 64 samples were collected from the Kazhdumi Formation (Albian) of south Zagros Basin (Coastal Fars Zone) in order to study the biostratigraphy and analyse the lithofacies. Stratigraphic distribution of identified larger benthic and planktonic foraminifers has confirmed the presence of three successive biozones: Mesorbitolina subconcava‐Orbitolina discoidea Zone, Favusella washitensis Zone followed by an upper Conicorbitolina conica‐Mesorbitolina parva Zone. Generally, orbitolinids are well developed in the Albian succession in the studied section, whereas the stratigraphic distribution of planktonic foraminifers is more restricted, dominating the Favusella washitensis Zone. Nevertheless, microscopic investigation recognizes five microfacies consisting of extraclast‐foraminifer packstone, peloid‐intraclast Orbitolina wackestone, foraminiferal plankton wackestone, intraclast‐Orbitolina grainstone, and coral‐rudist wackestone, which indicated a shallow water carbonates palaeoenvironment (intertidal, lagoon, bar) and open marine. The alternation of both planktic and benthic foraminifera through the Kazhdumi Formation confirms a rapid transgression and regression in the studied section during Albian time, which is attributed to Kazerun basement fault behaviour in the mentioned time interval.
