Dinosaur bonebed in Spain, Pantelosaurus (synapsid) study, and other news

From: Ben Creisler

A number of recent news stories:

Dinosaur bonebed found at Ariño in Spain was a freshwater marsh in a
subtropical climate (in Spanish)


The paper in Historical Biology that is mentioned is:

Uxue Villanueva-Amadoz, Luis Miguel Sender, Luis Alcalá, Denise Pons,
Rafael Royo-Torres & José B. Diez (2014)
Paleoenvironmental reconstruction of an Albian plant community from
the Ariño bonebed layer (Iberian Chain, NE Spain).
Historical Biology (advance online publication)

The AR-1 layer, corresponding to the Escucha Formation (Lower
Cretaceous) in the Santa Maria Mine of Ariño, has supplied rich and
well-preserved macrofloral and palynological assemblages showing
interesting data about both taphonomic and environmental conditions.
This single layer is located in the Oliete Sub-Basin from the
Maestrazgo Basin in northeastern Spain, and it represents one of the
most outstanding single layer fossil sites in the world. This site
shows abundant and diverse fauna containing exquisitely preserved
vertebrate and invertebrate fossils (dinosaur bones, turtles,
crocodiles, fishes, molluscs and ostracods) and also plant remains of
Albian age. The assemblage is especially significant for dinosaur
phylogenetic analysis. The sedimentary environment corresponds to a
freshwater swamp plain with sporadic marine inputs within a
deltaic–estuarine system under subtropical–tropical climate.
