Late glacial and Holocene Ostracoda from the Melilla cold-water coral mound field

Pirkenseer, Claudius M. ; Spezzaferri, Silvia ; Stalder, Claudio

In: Swiss Journal of Geosciences, 2018, vol. 111, no. 3, p. 549–560

The ostracod assemblages from sediment core TTR17-401G recovered from the Melilla cold-water coral mound field in the eastern Alboran Sea spanning the last 13 ka are analysed quantitatively, taxonomically and palaeoecologically. The core can be subdivided in three distinct assemblages linked to environmental shifts during the Younger Dryas and the Bølling–Allerød interstadial. A total of...

Re-evaluation of the Haarlem Archaeopteryx and the radiation of maniraptoran theropod dinosaurs

Foth, Christian ; Rauhut, Oliver W. M.

In: BMC Evolutionary Biology, 2017, vol. 17, p. 236

Archaeopteryx is an iconic fossil that has long been pivotal for our understanding of the origin of birds. Remains of this important taxon have only been found in the Late Jurassic lithographic limestones of Bavaria, Germany. Twelve skeletal specimens are reported so far. Archaeopteryx was long the only pre-Cretaceous paravian theropod known, but recent discoveries from the Tiaojishan...

A new species of Argyromys (Rodentia, Mammalia) from the oligocene of the valley of lakes (Mongolia): its importance for palaeobiogeographical homogeneity across Mongolia, China and Kazakhstan

López-Guerrero, Paloma ; Maridet, Olivier ; Zhang, Zhaoqun ; Daxner-Höck, Gudrun

In: PLOS ONE, 2017, vol. 12, no. 3, p. e0172733

We describe a new species of Rodentia (Mammalia), Argyromys cicigei sp. nov. from Toglorhoi (fossil bed TGW-A/2a) in Mongolia and Ulantatal (fossil beds UTL 1 and UTL 7) in China. Its tooth morphology differs from the type species Argyromys aralensis from Akespe in Kazakhstan by smaller size and simpler structures. Argyromys has been assigned in different families of Muroidea, such as...
