Could these be pictures of water horses or even Nessie?

Pictish carved beasts 'unlike anything found before'

A 1,200-year-old standing stone discovered in the Highlands has carvings never before seen on a Pictish stone, archaeologists have said.The stone was found lying in the ground and covered by vegetation at an early Christian church site near Dingwall.

Archaeologists have now revealed the side of the stone that was down in the earth and hidden from view was decorated with "two massive beasts".Just over a metre of the original two metre-tall (6ft) stone survives.The beasts were carved down the side of a cross.

John Borland, of Historic Environment Scotland and president of the Pictish Arts Society, said: "The two massive beasts that flank and surmount the cross are quite unlike anything found on any other Pictish stone."These two unique creatures serve to remind us that Pictish sculptors had a remarkable capacity for creativity and individuality.”

These fantastic beasts could be a representation of a sea serpent or a giant eel ,perhaps Nessie herself. They appear to have fierce heads with teeth and a long serpentine body.The dragon like appearance of the heads reminded me of Jurassic era  type  creatures or possible a conger eel which has sharp teeth.Certainly something to ponder in view of the DNA results from Loch Ness and the legends  of wingless dragons or wyrms in Scotland.
