A single maxilla is present in the well-preserved material of "Europasaurus", DFMMh/FV 291.17. This maxilla has a long body, with two elongate processes, a nasal and a posterior process. There is only a weak lacrimal process, like in most sauropods except "Rapetosaurus". The nasal process is elongate and covers the anterior and ventral rim of the antorbital fenestra. This process extends about 120º from the horizontal tooth row. The base of the nasal process also forms the body of the lacrimal process, and at their divergence is the antorbital fenestra, similar in shape to those of "Camarasaurus", "Euhelopus", "Abydosaurus" and "Giraffatitan", but about 1/2 taller proportionally. The pre-antorbital fenestra, a small opening in front of or beneath the antorbital opening, is well developed in taxa like "Diplodocus" and "Tapuiasaurus", is nearly absent, like in "Camarasaurus" and "Euhelopus". There were about 12–13 total teeth in the maxilla of "Europasaurus", fewer than in more basal taxa (16 teeth in "Jobaria" and 14–25 in "Atlasaurus"), but falling within the range of variation in Brachiosauridae (15 in "Brachiosaurus" to 10 in "Abydosaurus"). All of the unworn teeth preserved display up to four small denticles on their mesial edges. A small amount of the posterior tooth crowns are slightly twisted (~15º), but much less than in brachiosaurids (30–45º).
