BACKGROUND The best European locality for complete Eocene mammal skeletons is Grube Messel, near Darmstadt, Germany. Although the site was surrounded by a para-tropical rain forest in the Eocene, primates are remarkably rare there, and only eight fragmentary specimens were known until now. Messel has now yielded a full primate skeleton. The specimen has an(More)
The early Middle Eocene locality of Grube Messel, near Darmstadt (Germany), is famous for its complete vertebrate skeletons. The degree of preservation of soft tissues, such as body silhouettes, internal organs and gut contents, is frequently remarkable. The present specimen was analyzed for remnants of the reproductive system. Classic anatomy and osteology(More)
Darwinius masillae is a Haplorhine d Reply to Williams et al. (2010) Introduction A forty-seven-million-year-old primate Darwinius masillae from the middle Eocene of Messel in Germany is worthy of attention because it is one of the most complete fossil primates found to date (Franzen et al., 2009). Darwinius is exceptional because it demonstrates(More)
Since its discovery in 1938 Sangiran-3 has been considered a juvenile Pithecanthropus (Homo) erectus, and therefore, excluded from studies of adult H. erectus. Although morphological features align Sangiran-3 with H. erectus, its age designation rests on an unconvincing reconstruction of the occipital torus and lack of sutural fusion. Evaluation of the(More)
