(Journal of Foraminiferal Research, Gennaio 2015) E' stata istituita una nuova famiglia, genere e specie denominata "Robertonella rettorii", quale riconoscimento al contributo che il Prof. Roberto Rettori, del Dipartimento di Fisica e Geologia dell' Universita' degli Studi di Perugia, ha dato alla Micropaleontologia. Tale riconoscimento e' contenuto in un articolo di Rigaud, Martini e Vachard dal titolo "Early Evolution and New Classification of the Order Robertinida (Foraminifera)", che e' stato pubblicato in "Journal of Foraminiferal Research", v. 45, no. 1, p. 3-28, January 2015.
- Genus "Robertonella" n. gen.
- Type species: "Robertonella rettorii" n. gen., n. sp.
- Derivatio nominis: The new genus is dedicated to Roberto Rettori (University of Perugia, Italy) for his contributions to foraminiferal studies.
Article's Abstract:
"The discovery of Triassic missing links in the Panthalassan domain (Wallowa terrane, U.S.A.) substantiates a direct lineage between internally simple Triassic multichambered aragonitic foraminifers and internally partitioned Jurassic Robertinida. A new hierarchical subdivision is accordingly proposed for the order Robertinida, which is emended to encompass all known post-Paleozoic aragonitic multichambered foraminifers. At the highest taxonomic level, the suborder Robertinina is distinguished from the suborder Duostominina emended to encompass forms without internal structures attached to the aperture, including the planktonic family Favusellidae and the controversial form Pragsoconulus. Two new families (Robertonellidae, Trochosiphoniidae), four new subfamilies (Cassianopapillariinae, Praereinholdellinae, Pragsoconulinae, and Trochosiphoniinae), four new genera (Falsorheinoldella, Praerheinoldella, Robertonella, and Trochosiphonia), and seven new species (Falsorheinoldella ohmi, F. oregonica, Praerheinoldella galei, Robertonella rettorii, R. wallowensis, Trochosiphonia stanleyi, and T. josephi) are introduced. Phylogenetic links between Triassic robertinids, which experienced a rapid diversification during the Triassic, are clarified and their hypothetical long-term relationships with other foraminiferal groups are discussed."
