“…The Pisco Basin is renowned for hosting a very outstanding marine vertebrate Fossil-Lagerstätten (e.g., Colbert, 1944;Marocco and Muizon, 1988a;Muizon, 1988;Brand et al, 2004Brand et al, , 2011Esperante et al, 2008Esperante et al, , 2015Uhen et al, 2010;Bianucci et al, 2015Bianucci et al, , 2018aBianucci et al, , b, 2020Lambert et al, 2015Lambert et al, , 2018Lambert et al, , 2020Lambert et al, , 2021Stucchi et al, 2016;Di Celma et al, 2018Boskovic et al, 2021;Bosio et al, 2021b;Bianucci and Collareta, 2022), but also for J o u r n a l P r e -p r o o f remarkable finds of fossil invertebrates (e.g., Alleman, 1978;DeVries, 1988;DeVries and Frassinetti, 2003;Bosio et al, 2021a;Kočí et al, 2021;Sanfilippo et al, 2021) as well as for microfossil studies (e.g., Mertz, 1966;Macharé and Fourtanier, 1987;Schrader and Ronning, 1988;Marty, 1989;Tsuchi et al, 1988;Koizumi, 1992;Ibaraki, 1993;Gariboldi, 2016;Coletti et al, 2019a;. As regards the fossil invertebrates, the Chilcatay Formation features an abundant and rather diverse fauna comprised of mollusks, acorn barnacles, cirratulids, echinids, brachyuran decapods, and rare bryozoans and benthic foraminifera (Coletti et al, 2018;Di Celma et al, 2018b).…”
