National Geographic has a story about Juravenator starki.  This animal lived about 150 million years ago, during the Jurassic Period, in what is now Germany.   A new paper, in the journal Current Biology, proposes that it might have used sensory scales on its tail to sense fish when it foraged at night.

A CHICKEN-SIZE DINOSAUR that lived in what is now Germany about 150 million years ago might have used sensory scales on its tail as it foraged for fish at night. These sensory organs, remarkably similar to those found on a crocodile, likely helped the animal suss out its environment as it waded across the shallow lagoons of a prehistoric archipelago that once covered Europe.

“Skin only rarely preserves in the fossil record, so when we try to imagine living dinosaurs from just bones, details about their external body coverings are often speculative,” says Stephanie Drumheller-Horton of the University of Tennessee, Knoxville, who was not involved with the new research. “Soft tissues can really flesh out our interpretations of these groups.”
