REMARKABLE LATE CRETACEOUS FOSSILS FROM LIÈGE-LIMBURG
Part 42. A squid with bite marks
A single rostrum of the belemnitellid coleoid Belemnitella junior Nowak, 1913,
presumably from interval 6 of the Vijlen Member (Gulpen Formation; upper lower
Maastrichtian) as exposed at the Kreco quarry (Haccourt, Liège), has a dense cover of
episkeletozoans (oysters, serpulid polychaetes, bryozoans and
... [Show full abstract] foraminifera). In addition,
it shows a set of four to six parallel, deep to shallow scratches that are accompanied
by four shorter, even shallower grooves on the other side of the rostrum. Attempts are
made to link these bite marks to some predator or scavenger. The heterodont dentition
of a bullhead shark of the genus Heterodontus fits the pattern of scratches fairly well,
although it may also have been caused by another type of shark – or a completely
different type of predator or scavenger.
