Brief SummaryRead full entry
Dolichorhynchops osborni is an extinct species of marine reptile. The genus was named for its elongated rostrum and literally translates to “long snout face”. Dolichorhynchops osborni is a short-necked plesiosaur, a unique lineage of predatory marine reptiles. Relatively smaller compared to some of its pliosaur cousins, D. osborni only grew as large as 5-6 m (16-20 ft.) in length (Everhart, M., 2004). It lived in the Late Cretaceous (Early Uronian to Late Campanian, ~93.5-70.6 mya) in the Western Interior Seaway (McKean, R., 2012).
