The alveolinids were once highly widespread in the Cenomanian of the Tethys Basin. Even though evolutionary studies have, thus far, been conducted using material from many countries e.g. Spain, Oman, and the UAE, the Zagros region in SW Iran has not been studied yet. Two sections of the Sarvak Formation in the Pyun and Kuh‐e‐Zana areas were investigated. Five type levels can be identified in the Pyun section. The evolutionary trend begins with praealveolinids followed by ovalveolinids in the Early Cenomanian. Cisalveolinids firstly appear in the Late Cenomanian strata and then Multispirina is derived. Then Simplalveolina simplex appears, which is derived from Multispirina iranensis. At the Kuh‐e Zana section, the evolutionary trend was observed in three levels. There is no ideal evolutionary trend because Multispirina and Simplalveolina are absent in this section. The identified trends are similar to those of the Iberian Ranges in Spain.

The Sarvak Formation is a carbonate sequence of Late Albian-Early Turonian age in Zagros Basin in Iran. In this investigation, the Sarvak Formation at the Pyun Anticline section (Izeh Zone) has been studied. It consists of 797 m thick limestone which overlies the Kazhdumi Formation conformably and underlies the Gurpi Formation unconformably at the Pyun Anticline. A very rich fossil association (85 genera and 132 species) characterizes the Pyun section. Based on the stratigraphic distribution of diagnosed foraminifera, five biozones are established: 1, Muricohedbergella-Globigerinelloides sp. assemblage zone (Late Albian); 2, Praealveolina iberica-Chrysalidina gradata interval zone (Early Cenomanian); 3, Chrysalidina gradata-Cisalveolina fraasi (fallax) and C. lehneri interval zone (Middle Cenomanian); 4, C. fraasi (fallax) and C. lehneri-Praetaberina bingistani assemblage zone (Late Cenomanian); 5, Nezzazatinella picardi-Mangashtia-Dicyclina assemblage zone (Early Turonian). Based on the petrographic and sedimentological analyses, some 13 carbonate microfacies were identified. The investigated microfacies confirm a ramp-type paleoenvironment. These microfacies, from distal to proximal environments, consist of: MF1:

In this manuscript, Notes to comment on "Evolutionary trend of Cenomanian alveolinids from Zagros Basin, SW of Iran" by Consorti and Vicedo (2022) in Geological Journal, will be answered. Received data coincided with the previous determination of the alveolinids microscopic investigation and corresponded with the biostratigraphical database remarkably. No contaminated data were recognized in this work and the faunal assemblage in the Sarvak Formation was checked in detail. Both Cenomanian shallow water and pelagic sediments of the Sarvak Formation in the Zagros Basin are well-known oil reservoir rocks. The Formation has been studied from the point of view of biostratigraphy, facies analysis, and sequence stratigraphy (Arampour, Afghah, &
