Plicofollis nella (n= 33) ( Fig. 6, Supplementary data 8)

These lapilli are quite similar to the P. argyropleuron ’s, in terms of the features of their mesial and distal margins, that makes them also appear diamond shaped. However, here some of the otoliths tend to have small protrusions on the outermost part of their mesial margin, typically near to the middle but slightly towards the anterior margin. They have prominent Amp and some of them have tubular curved Sl (n= 22), and others are compactly curved (n= 11). Their Mn appears slightly compressed, and a few have shallow ILb (n= 13), while the remaining have deep ILb (n= 20).
