Early Cretaceous amber (Lower-Middle Albian) is abundant in Spain and numerous and diverse arthropod inclusions have been recovered and reported (e.g., Delclòs et al. 2007, Peñalver & Delclòs 2010 ), to date there has been no record of Dermaptera from any of these deposits. It is therefore noteworthy

deposits of the Chubut Group (see Carballido et al. 2017 ). These sediments belong to the Cerro Castaño Member of the Cerro Barcino Formation and dating of associated tuffs indicates they are upper Albian (101.6 ± 0.11 Ma; Carballido et al. 2017 ). The flora consists of impressions and compressions

Cruickshank and Ko (2003) reviewed the geology of the burmite deposits, and proposed a late Albian age. Recently it was possible to give an absolute age of the

Fossil woods are abundant in the Cretaceous Yezo Group in Hokkaido, Japan, in strata of Albian to Santonian ages. From 144 dicotyledonous samples, fourteen species representing 10 genera were identified: Castanoradix cretacea gen. et sp. nov., C. biseriata gen. et sp. nov., Frutecoxylon yubariense gen. et sp. nov., Hamamelidoxylon obiraense sp. nov., Icacinoxylon kokubunii sp. nov., I. nishidae sp. nov., Magnoliaceoxylon hokkaidoense sp. nov., Nishidaxylon jezoense gen. et sp. nov., Paraphyllanthoxylon cenomaniana sp. nov., P. obiraense sp. nov., Plataninium jezoensis sp. nov., P. ogasawarae sp. nov., Sabiaceoxylon jezoense gen. et sp. nov. and Ulminium kokubunii sp. nov. All 14 species are new and four of the 10 genera are new. Five genera (lcacinoxylon, Magnoliaceoxylon, Paraphyllanthoxylon, Plataninium and Ulminium) already are known from the Cretaceous and Tertiary, one (Hamamelidoxylon) previously is known only from the Tertiary. The species distribution by age is: Albian: one species; Cenomanian: four species in four genera; Turonian: ten species in eight genera; Coniacian: six species in five genera; Santonian: eight species in seven genera. The two specimens of Icacin oxylon kokubunii from the Albian are the oldest records of dicotyledonous woods in Japan.

Two new brachyuran species are described for the Upper Cretaceous Mexcala Formation, Guerrero State, Mexico. Longusorbis quadratus new species (Coniacian, Temalac region) is the oldest and southernmost record for the genus. Xanthosia zoquiapensis new species (Campanian, Zoquiapa region) is the first record for the genus in Mexico. In addition, the age for Costacopluma bishopi Vega and Feldmann is discussed (Coniacian, Temalac region) and represents the oldest and southernmost record for Cretaceous representatives of this genus in North America. All specimens are considerably smaller compared to other species of the same genera and are interpreted as the first example of brachyuran dwarfism in the geological record. These species add new insight into possible migratory routes during the Late Cretaceous. Within Longusorbis, a northwestern migratory route is documented from the Coniacian in Mexico to the Campanian - Maastrichtian of the west coast of North America (Canada), whereas within the genus Xanthosia, a western migratory route from the Albian of Europe to the Campanian of Mexico is indicated. Costacopluma migrated east and north to the west coast of Africa, southeast North America and Greenland.

Three new wood types from the Late Cretaceous and one from the Paleocene of Big Bend National Park, Texas, U.S.A. add to our knowledge of North American Late Cretaceous and Paleocene plants. Sabinoxylon wicki sp. nov. provides further evidence of similarities in late Campanian-early Maastrichtian vegetation of Texas, New Mexico, and northern Mexico. This species is characterized by mostly solitary vessels, scalariform perforation plates, vessel-ray parenchyma pits similar to intervessel pits, vasicentric tracheids, and two size classes of rays. Storage tissue accounts for close to 50% of its wood volume. Another of the new Cretaceous wood types, referred to as Big Bend Ericalean Wood Type I, has more than 40% ray parenchyma. Both Big Bend Ericalean Wood Type I and Sabinoxylon have a combination of characters that occurs in the order Ericales (sensu APGII). The third new Cretaceous wood type is from a small axis (less than 3 cm diameter), and has a combination of features that is the most common pattern in extant eudicots (vessels solitary and in radial multiples randomly arranged, simple perforation plates and alternate intervessel pits, and heterocellular rays). The Paleocene wood (cf. Cunonioxylon sensu Gottwald) differs from all other North American Paleocene woods and has characteristics found in the predominantly Southern Hemisphere family Cunoniaceae. The characteristics of these new Big Bend woods contribute to a database for fossil angiosperm woods, and allow for comparison of incidences of selected wood anatomical features in Northern Hemisphere Cretaceous woods from Albian to Maastrichtian time as well as comparison with extant woods. Cretaceous woods as a whole differ from Recent woods in having higher incidences of exclusively solitary vessels, scalariform perforation plates, and wide rays (>10-seriate), and lower incidences of ring porosity, wide vessels (>200 μm), vessels in groups, non-random arrangements of vessels, and marginal parenchyma. The occurrence of relatively high percentages of storage cells (>40%) in some Cretaceous trees is noteworthy; the ability to produce wood with varying amounts and arrangements of parenchyma is likely to be a contributing factor to the success of angiosperm trees in a wide variety of environments.

evidence, this site was dated to the late Albian of the Early Cretaceous (Cruickshank & Ko, 2003 ), placing the age at 97-110 Ma. A more recent study using U-Pb zircon dating determined the age to be 98.79 ± 0.62 Ma or at the Albian/Cenomanian boundary (Shi et al ., 2012 ). Nuclear magnetic resonance
