Collection of picked and determined benthic and planktic foraminifera from the section of Cretaceous Scaglia and Flysch formations exposed along Breggia River in southern Switzerland. The collection includes the holotypes illustrated in Gandolfi's PhD thesis (type collection), a vast collection of picked specimens in fema cells, and thin sections. A copy of the publication is deposited with the material.

New specimens from the Gandolfi (1942) collection were also described by Manfred Reichel, see collection Reichel, M. (1949a)., and the sub-collection of original microfossil specimens within the collection of structural foraminiferal models of Manfred Reichel.

Note [21 August 2015]:
Study material from the Gandolfi collection was also investigated in the later dissertation by Jakob Schweighauser (1953) and is now deposited in the study collection ("Breggia") of J. Schweighauser. This material contains small amounts of washed residues and few unprocessed chips of sediment, that were originally collected by Gandolfi or given to him by colleagues (for example L. Vonderschmitt, see the foreword in Gandolfi, 1942). Samples are labelled with R.G. (from Rolando Gandolfi) and bear numbers illustrated in the stratigraphic column illustrated in Tavola 1 of Gandolfi (1942). See the study collection of J. Schweighauser.




Note #1:

According to Caron, M. (personal communication 20.6.2006) there is a mis-identification of specimens between the holotype and a topotype of Globotruncana appenninica Renz. The slide in the Gandolfi collection, which holds Globotruncana appenninica Renz s.str. (Breggia, strato 55), bears a pencil-writing "holotype" of H.P. Luterbacher. However, the slide contains two specimens: One is identifiable as the specimen illustrated in Luterbacher and Premoli Silva (1962), on plate XIX, fig. 3a-c, which is a topotype (see figure below). The other is a broken specimen (is this perhaps the holotype ?). The holotype as illustrated in Gandolfi (1942), pl. II, fig. 5a-d (see below), is, however, not known.





























Note #2:
In 2010/2011 G. ticinensis and G. renzi from the R. Gandoldi collection were re-investigated by Brian T. Huber (Smithsonian Institution, Washington D.C., U.S.A.), who isolated Globotruncana ticinensis metatypes from the specimens from sample Br. 29 and a Globotruncana renzi Gandolfi metatype from the specimens in the sample from Balerna.


Note #3:
There is additional material from the Breggia section that was re-collected by H.P. Luterbacher and Michèle Caron: See Study collns H.P. Luterbacher: Topotypes from various locations, mostly Europe.
