| A new spinosaurid taxon, Oxalaia quilombensis gen. et sp. nov., is described based on the anterior part of a snout and a fragment of a maxilla. These specimens were collected at the Laje do Coringa site, Late Cretaceous (Cenomanian) of the São Luis Basin. Unlike Cristatusaurus and Suchomimus, Oxalaia quilombensis lacks serrations on the teeth. The new species differs from Angaturama limai by having the anterior part of the premaxillae more expanded and by lacking a sagittal premaxillary crest. It further differs from Spinosaurus cf. S. aegyptiacus and the Algerian spinosaurid by the rounder shape of the terminal expansion. Furthermore, xalaia quilobensis has one functional tooth followed by two replacement teeth, a feature not previously observed in... |

| A single, slightly laterally compressed carapace of a dromioid crab from the middle/upper Albian part of the Kazhdumi Formation in the Hamiran area (Hormozgan Province, southwest Iran) is described as a new species, which is tentatively assigned to the brachyuran genus Distefania Checchia-Rispoli, 1917, D.(?) tangishirazensis. This constitutes the first record of the genus from the Middle East. In addition, from the long-defunct Rauen quarry at Kassenberg, near Mülheim-Broich (northwest Germany), a carapace of D. incerta and a rather battered cheliped of the ‘form genus’ Roemerus Bishop, 1983 are recorded from the upper Cenomanian portion of that section, thus adding to previous records of these taxa from Germany. |
