I don't think these have been mentioned before:

Vertebrate dinoturbation from the Caturrita Formation (Late Triassic,Paraná 
Basin), Rio Grande do
Sul State, Brazil.

The Caturrita Formation is a lithostratigraphic unit that comprises the 
sequence of the Paraná Basin. It has been interpreted as deposits of alluvial 
plains and
meandering rivers. Purported fossil tracks found in this formation at Faxinal 
do Soturno County,
Rio Grande do Sul State, Brazil, are concave circular-shaped structures, with a 
deformation. Some show digitiform projections, and at least three are aligned. 
They are
interpreted as a disruption of the substrate homogeneity caused by bioturbation 
of tetrapods. In
some of these there is a distinct
color pattern â?? more reddish than the surrounding substrate. This is 
interpreted as a result of
differential diagenesis. The features remain enigmatic tracks but were probably 
made by
prosauropod dinosaurs, the dominant terrestrial herbivore group from the end of 
the Triassic in
Gondwana strata.

Notes on fossil remains from the Early Cretaceous Lohan Cura Formation, Neuquen

In this contribution, we describe an association of fossil remains collected in 
the locality of
Cerro de Los Leones, approximately 8 kmsouthwest of the town of Picún Leufú, 
Neuquén Province,
Argentina, from different levels of the Albian Cullín Grande Member, Lohan 
Cura Formation. The
fossils include pelecypodan (Neocorbicula dinosauriorum, Neocorbicula 
pehuenchensis, and genus
indet.) and gastropodan (Physa wichmanni) molluscs, a mesoeucrocodylian, 
possible pterosaurs,
theropods, and sauropods. The sedimentary environment at Cerro de los Leones is 
characterized by
fluvial deposits corresponding to a sandy meandering fluvial system. The most 
fossiliferous levels
(located in the lower part of the exposed sequence) were developed in a distal 
flood plain and
flood basin areas. Sedimentological and paleopedological features suggest 
semi-arid conditions
during the deposition of the Cullín Grande Member. Despite the fragmentary 
nature of the
specimens described here, the new information provided from the Albian 
assemblages of the Lohan
Cura Formation at the Cerro de Los Leones locality provides a broader panorama 
of the composition
of terrestrial faunas during the Early Cretaceous in Patagonia.
