Where: Mahajanga, Madagascar (15.9° S, 46.6° E)

• Paleocoordinates: 36.6° S, 43.8° E (Wright 2013)

• coordinate stated in text

• local area-level geographic resolution

When: Berivotra Formation, Maastrichtian (72.1 - 66.0 Ma)

Environment/lithology: marine; lithified claystone

Size class: macrofossils

Collected in 1993, 1995, 1996, 1998, and 1999; reposited in the UCMP

Collection methods: bulk, sieve

• These were

•organized as joint endeavours of the University of

•Antananarivo, Madagascar, and Stony Brook

•University, New York.

•

•These specimens are currently

•housed at Stony Brook University as a study collection,

•and will be catalogued and deposited in the

•collections at the University of Antananarivo (UA),

•and the Field Museum of Natural History (FMNH

•PF).

•

•Many shark and ray teeth were collected by surface

•prospecting on outcrops of the Berivotra Formation,

•which is readily distinguished by its yellowish grey to

•pale olive colour, as opposed to the white and green

•fluvial sandstones that form the upper 15–20 m of

•the underlying Maevarano Formation. Additional

•specimens were recovered (by JAR and LLR) by

•sieving, using a mesh size down to 2 mm, and by

•picking fossiliferous concentrate under a microscope.

•Drawings of specimens were made using a camera

•lucida attachment on a Leica MZ8 stereoscopic

•binocular zoom microscope.
