The historical collections of Liege University were amassed mainly by Gustave Dewalque (1826-1905), who 
held the chair of geology between 1857 and 1897. They include a large number of animal macrofossils from 
the Cretaceous of southern Belgium, but also from elsewhere in western Europe (e.g., France, the 
Netherlands and Germany, for the most part). Nevertheless, these collections remain largely unknown to 
the palaeontological community. This is obviously related to the fact that, contrary to their Palaeozoic 
counterparts (see Mottequin e t  al., 2011), they have been barely studied. One of the few papers dealing 
with Belgian Late Cretaceous material housed at Liege University is that by Cotteau (1875); in this the 
echinoids from the Cenomanian Bernissart Calcirudites Formation (formerly the 'Tourtia de Tournai') are 
discussed. However, these collections are of considerable significance as they comprise lots of specimens 
originating from localities which are no longer accessible, such as Rocourt and Thimister. 
The core of the Campanian-Maastrichtian collections consists of several tens of thousands of invertebrate 
specimens (e.g., ammonites, belemnites, nautiloids, bivalves, brachiopods, bryozoans, echinoderms, 
gastropods, scleractinians, sponges, foraminifera and decapod crustaceans), which essentially come from 
the Liege area (e.g., Rocourt, Thimister, Montagne Saint-Pierre) and the Mons Basin (e.g. Ciply, Spiennes), 
but also from France and the Netherlands. Most of them are still mounted on their original cardboard 
tablets. Vertebrates from the same regions, which are clearly less abundant, are represented by teleosts, 
chondrichthyans, diverse mosasaurids, large elasmosaurid plesiosaurians, and probably two different taxa 
of marine turtles, including one large form. lchnofossils constitute only a minor part of these collections. 
Some type specimens are housed at Liege University. Among the echinoids, we may cite the type of 
Micraster? ciplyensis Schluter, 1897, allegedly from the Maastrichtian of Ciply. In spite of our efforts, the 
type of Leymeriaster maestrichtensis (Schluter, 1897) (Maastricht Formation, Maastrichtian), reported by 
Schluter (1897) to be part of the Liege collections, has not yet been traced (see also Meijer, 1955). Also 
worth noting are the types of the ichnofossil Taonurus saportai Dewalque, 1881 from the 'Senonian' of 
northern France (Anzin).

Cretaceous rocks, unconformably resting on the Palaeozoic basement, are recognised in several regions 
within the southern and northeastern parts of Wallonia, mainly in the Mons Basin and the Liege area, 
respectively (e.g., Robaszynski et al., 2002). In northeast Wallonia (Fig. l ) ,  Upper Cretaceous deposits 
essentially include sands, chalks and calcarenites. Northwest of Liege, they are generally covered by 
Cenozoic (Paleogene) and/or thick loess deposits. Campanian and Maastrichtian carbonate rocks (Gulpen 
and Maastricht formations) are still extensively quarried for the production of Portland cement in the 
valleys of the Meuse and Geer rivers, north of Liege. They are also excellent reservoir rocks, affected by a 
double porosity (Dassargues & Monjoie, 1993), and constitute the Hesbaye aquifer, which is crucial for the 
water supply of Liege and i t s  suburbs.
