    Hi guys,

    Any one know of a turtle with an attitude on the Miocene of Florida? The peace River was to high (covering trees high) so went to creeks close by. Found two of this (photos below represent one) turtle shells, to my surprise they have some nasty spikes. Anyone can help with an ID?

    Regards,

    Alex
