Recently discovered tracks in alluvial sediments of the Late Paleocene Bullion Creek Formation of western North Dakota have been identified as belonging to the large eusuchian crocodile Borealosuchus formidabilis and an associated small arthropod. They are described as two new ichnotaxa. The first of these, Borealosuchipus hanksi igen. et isp. nov., is based on a partly complete trackway having fore- and hind-footprints as well as body marks preserved in hyporelief. These tracks are directly… 

Horseshoe crab trace fossils from the Upper Cretaceous Two Medicine Formation of Montana, USA, and a brief review of the xiphosurid ichnological record

Abstract. A locality in the Upper Cretaceous Two Medicine Formation of Montana preserves abundant and variable horseshoe crab tracks and trails of the ichnotaxon Kouphichnium isp. These specimens

Trackway evidence for large bipedal crocodylomorphs from the Cretaceous of Korea

This interpretation helps solve previous confusion over interpretation of enigmatic tracks of bipeds from younger (? Albian) Haman Formation sites by showing they are not pterosaurian as previously inferred, and support the strong consensus that pterosaurs were obligate quadrupeds, not bipeds.

THE NON-DINOSAUR TRACKS AT THE LATE CRETACEOUS

The Cherryvale tracksite, a Maastrichtian age Laramie Formation site discovered in 2016 southeast of Boulder, Colorado, has yielded dozens of dinosaur tracks reported by Lockley and the present

American crocodile footprints and trackways are similar to those observed in other extant crocodylian species, indicating substantial trackway conservatism across the group.

WANNAGANOSUCHUS, A NEW ALLIGATOR FROM THE PALEOCENE OF NORTH AMERICA

A new genus and species of alligator, Wannaganosuchus brachymanus, is described on the basis of a single, nearly complete, skeleton from the Paleocene, Bullion Creek Formation of western North Dakota, which provides an essentially complete osteology, including a suite of osteoscutes.

The fossil trackway Pteraichnus; not pterosaurian, but crocodilian

Experimental work on trackways coupled with considerations of limb kinematics and substrate conditions will permit the most robust inferences about paleoichnologic trackmakers, and will thus maximize the utility of fossil footprint data.

Aspects of some anatomical structures of Champsosaurus(Reptilia: Eosuchia)

The essentially complete articulated postcranial skeleton indicates that the ribcage was relatively rigid and Gastralia functioned with this rigid unit in compression and expansion of the pleural cavity and lowered the center of gravity to assist in underwater stability.

Diversity of life

It is clear that the above can lead to confusion when scientists of different countries are trying to communicate with each other, so an internationally recognized system of naming organisms is created.
