Underwater dino tracks found, according to reports in ScienceNOW, BBC News, 24 May 2007, and ABC (Australia) News in Science and New Scientist  25 May 2007. A team of Spanish and French palaeontologists have found a series of dinosaur toe prints preserved in sandstone in the Cameros Basin in northern Spain. The track consists of twelve sets of imprints, each consisting of two orthree S-shaped impressions consistent with the toes of a theropod dinosaur – two legged like T rex. The rock also has well preserved current ripple marks, which a sedimentologist on the team claimed were made by flowing water 3.2 metres deep. The toe marks were on average 15 cm wide and 50 cm long. The creature that made them had a stride of about 2.5 metres and had its legs spread about44cm apart. These findings indicate the imprints were made by a large dinosaur battling its way against a strong current. Palaeontologist David Fastovsky of the University of Rhode Island commented the dinosaur was not swimming, since its toes were touching the ground, although he believes they could swim in deeper water if they had to.

Editorial Comment: The fact that both the tracks and ripple marks were preserved means they were rapidly buried by another layer of sediment before they eroded. This, combined with the picture of large dinosaur struggling against deep fast flowing water, should make people think of a flood current, not slow gradual processes.(ref. catastrophism, deposition, fossilisation)
