These faint fossils of two juvenile seahorses, called Hippocampus slovenicus, are among the oldest seahorse fossils ever found, scientists said in April 2009.

The new finds suggest that the fish could have held onto floating clumps of seagrass for weeks or months with their prehensile tails. If caught in a current, these rafts of seagrass may have carried the seahorses as far as 160 miles (260 kilometers) in a month--possibly explaining how the poor swimmers were able to spread around the globe.
