(2022).- A larger benthic foraminiferal zonation for the Eocene of the Caribbean and central American region.- Carnets Geol., Madrid, vol. 22, no. 11, p. 409-565. , available online at https://doi.org/10.2110/carnets.2022.2211
Figure 75: Specimens from the type material of Polylepidina chiapasensis Vaughan, 1923. 1, off-centre equatorial section (USNM 269273), cut from same block as type specimens. 2, off-centre equatorial section (USNM 324726), figured by Vaughan, 1929a. Note that both have two PACs (although difficult to see in 1) and that the PACs are of similar size in 2; note two spirals with asymmetrical closing chamber (cc) in 2. Since these are off-centre sections we do not see all the peri-embryonic spires that are developed; 2 clearly shows two spires developing from two large PACs and a closing chamber (cc) that is asymmetrical to the spire development.
