In Bolivia, numerous dinosaur tracks (1,275) have been found in Torotoro National Park, as described in Plos (full article available!). These include individual and group tracks. The parallel tracks seem to indicate group behaviour. Walking and swimming behaviour has been further investigated, as has tail swishing. This research dwarfs the recently found track in England. Unfortunately, few bones have been found to supplement the tracks. The photo is of a track in Portugal.

After being domesticated in Egypt around 5,000 years ago, domestic cats were brought to Europe by the Romans only around 2,000 years ago. This has become known from new DNA research, as published in Science.

Further investigation into the damage to the lower vertebrae of hadrosaurs suggests that this damage is structural. It is possible that the male damages the vertebrae during mating. This is the hypothesis of Canadian palaeontologist Darren H. Tanke, published in the leading journal Cell. 

Many beautiful fossils dating back 505 million years, to the Middle Cambrian period, have recently been found in the Grand Canyon (USA, Arizona). An article about this can be read in full at ScienceAdvances. In addition to small molluscs and crustaceans, Priapulida (penis worms) have also been found.

The film in the link above to CNN is also very interesting to watch. Drawing from Wikipedia.
