Shell characterization of the youngest valid species of the European Eocene genus Neochelys (Pleurodira, Podocnemididae): The Spanish Bartonian Neochelys salmanticensis

The Anatomical Record, Volume 308, Issue 6, Page 1553-1572, June 2025.
Abstract The freshwater pleurodiran turtle Neochelys is the best‐represented member of Podocnemididae in the European record, being known by eight Eocene species. The youngest of them is the Bartonian (middle Eocene) Neochelys salmanticensis, from the Duero Basin (Salamanca Province, Central Spain).

A new Crocodyloidea from the middle Eocene of Zamora (Duero Basin, Spain)

The Anatomical Record, Volume 308, Issue 6, Page 1692-1706, June 2025.
Abstract The eusuchian crocodyliforms recorded in the Eocene levels of the Spanish Duero Basin belong to three lineages: Planocraniidae, with the species Duerosuchus piscator; Alligatoroidea, represented by several specimens of the genus Diplocynodon; and Crocodyloidea, which includes several specimens traditionally attributed to Asiatosuchus.

A bothremydid turtle (Pleurodira) from the middle Cenomanian of Vale de Figueira (Belas, Portugal)

The Anatomical Record, Volume 308, Issue 6, Page 1573-1579, June 2025.
Abstract An unpublished turtle shell from the middle Cenomanian of Vale de Figueira, near Belas (Lisbon District, Portugal), is recognized by us as collected in 1880 under the direction of Carlos Ribeiro. No turtle remains from that region had so far been figured, described or discussed from a systematic point of view.

Subcritical water-ethanol treatment for sugar cane trash biomass fractionation: An experimental study of the effect of process conditions on simultaneous delignification and hydrolysis

Industrial Crops and Products
Biomass fractionation by delignification and hydrolysis of sugar cane trash with subcritical water-ethanol treatment was investigated by experimental factorial design in which temperature and ethanol volume percent (v.%) were the assessed factors.
