“…In addition, one new species of alveolinid, Borelis hottingeri, and one new species of rotaliid, Dictyoconoides boneti, have been identified among the material studied. The two foraminiferal associations in Campeche described in this paper, interpreted as deposits of an inner to middle ramp setting, together with those defined in Chiapas by VICEDO et al (2013) characterize the Paleocene of southern Mexico. Combining data from these two studies, the estimated age for the two assemblages of Campeche is Thanetian (SBZ 3?…”

“…In our work, the data obtained from different isolated outcrops in Campeche, and those from Chiapas (VICEDO et al, 2013), make it possible to comment on the ecological requirements of the morphotypes studied from the Paleocene times in the Caribbean area.

“…The larger foraminifera associations defined in VICEDO et al (2013) for the Paleocene of Chiapas State (SE Mexico), one of them with Taberina cubana KEIJZER, 1946, and the other one with Ranikothalia bermudezi (PALMER, 1934), are younger than, at least, the association of R. soldadensis. More regional stratigraphic studies are needed, however, to constrain the ages and the paleobiogeographic distribution of all the assemblages.…”

“…This biozonation cannot be extrapolated to the Caribbean paleobioprovince because the Paleogene larger foraminifera of that area are still poorly known and taxonomic revisions are needed in order to clarify their taxonomic and biostratigraphic position.

This paper focuses on the enhancement of the biostratigraphic value of the larger foraminifera taxa found in the Paleocene rocks of the Yucatán Peninsula (SE Mexico).…”

Abstract:The larger foraminifera found in the material from the Chichen Itzá Formation of Campeche (SE Mexico) were studied in detail. The architectural analyses allow the description of four new species and a new genus, namely, two agglutinated conical foraminifera, Coskinolina yucatanensis n.sp. and Pseudofallotella drobneae n. gen. n.sp., one new alveolinid, Borelis hottingeri n.sp., and one new rotaliid, Dictyoconoides boneti n.sp. The larger foraminifera of the Chichen Itzá Formation are distributed across two different associations: one includes Pseudofallotella drobneae, Neotaberina sp., Rhabdorites sp., Borelis hottingeri, Dictyoconoides boneti, Kathina sp., Miscellaneidae, Ranikothalia soldadensis and Hexagonocyclina cristensis, while the other assemblage is composed of Coskinolina yucatensis, Fallotella causae, Rhabdorites sp., Borelis floridanus and Cincoriola cf. ovoidea. Some of these genera, including Neotaberina and Dictyoconoides, are cited in the Caribbean paleobioprovince for the first time in this paper. The first association is dated as Thanetian (SBZ 3? to SBZ 4) by the presence of Ranikothalia soldadensis. Though the age of the second association remains uncertain, a similar age has been inferred.Key Words: Paleocene; Yucatán; Mexico; larger foraminifera; biostratigraphy. Résumé : Les grands foraminifères paléocènes de la péninsule du Yucatán (SE du Mexique).-Les grands foraminifères observés dans du matériel provenant de la Formation Chichen Itzá de l'État de Campeche (SE Mexique) ont été étudiés en détail. Des analyses de leur architecture ont permis de décrire quatre nouvelles espèces et un nouveau genre, deux foraminifères coniques à test agglutinant, Coskinolina yucatanensis n.sp. et Pseudofallotella drobneae n.gen. n.sp., un nouvel alvéolinidé, Borelis hottingeri n.sp., et un nouveau rotaliidé, Dictyoconoides boneti n.sp. Les grands foraminifères de la Formation Chichen Itzá sont groupés dans deux associations distinctes : une première avec Pseudofallotella drobneae, Neotaberina sp., Rhabdorites sp., Borelis hottingeri, Dictyoconoides boneti, Kathina sp., Miscellaneidae, Ranikothalia soldadensis et Hexagonocyclina cristensis, une seconde avec Coskinolina yucatensis, Fallotella causae, Rhabdorites sp., Borelis floridanus et Cincoriola cf. ovoidea. Quelques-uns de ces genres, notamment Neotaberina et Dictyoconoides, sont signalés ici pour la première fois dans la province paléobiogéographique caraïbéenne. La première association est datée du Thané-tien (SBZ 3? à SBZ 4) du fait de la présence de Ranikothalia soldadensis. Bien qu'il y ait encore une incertitude quant à l'âge de la seconde association, nous avons retenu la même position stratigraphique.

The palaeobiogeography of the alveolinoid Borelis species reveals the evolutionary patterns leading to the two extant representatives, which occur in shallow‐water tropical carbonate, coral reef‐related settings. Type material and new material of fossil Borelis species, along with Recent specimens were studied to assess their taxonomic status, species circumscriptions (based on proloculus size, occurrence of Y‐shaped septula, and the index of elongation), palaeobiogeography and evolutionary dynamics. The species dealt with here are known from exclusively fossil (B. pygmaea, B. inflata, B. philippinensis, B. melo, B. curdica), and from fossil and modern (B. pulchra, B. schlumbergeri) specimens. For the first time, fossil and Recent Borelis specimens are illustrated via micro‐computed tomography scanning images. Depending on the occurrence of Y‐shaped septula, two lineages are distinguished. Deriving from the middle–upper Eocene Borelis vonderschmitti, the first lineage includes B. inflata, B. pulchra and B. pygmaea, lacking Y‐shaped septula. The first species bearing Y‐shaped septula is the Rupelian B. philippinensis of the western Indo‐Pacific. The westward migrants of B. philippinensis into the Mediterranean gave rise to B. melo (Aquitanian–Messinian) and B. curdica (Burdigalian–Tortonian). These two species became isolated from the Indo‐Pacific by the Langhian eastern closure of the Mediterranean basin and disappeared during the Messinian Salinity Crisis. Since the Tortonian, B. schlumbergeri, which descended from B. philippinensis, has inhabited the Indo‐Pacific along with B. pulchra. From the central Pacific Ocean, B. pulchra reached the Caribbean area before the early Piacenzian closure of the Central America seaway.

A deep architectural analysis of the Paleocene, porcelaneous larger foraminifera Taberina daviesi Henson, 1950 has been conducted for the first time, which has permitted clarification of its generic taxonomic attribution and a more accurate assessment of its palaeobiogeographical and biostratigraphical distributions. The crosswise oblique pattern followed by the stolon axes in T. daviesi differs from the radial pattern showed in the type species of the genus Taberina, T. cubana Keijzer, 1945. Moreover, differences in the embryonic architecture and the type of growth and final test shape between these species support a change in the generic taxonomic attribution. Thus, a new genus, Azzarolina, is proposed for the former species. Azzarolina daviesi is a common biostratigraphic marker for the Paleocene with a broad distribution in the Arabian Peninsula and surrounding areas.
