Ahh the might Siderops Kehli, the last of the giant temnospondyls to be found in the fossil record. Her amphibiousness served her well as she prowled the temperate lagoons of the Mid Jurassic sniping fish and small reptiles. Still debated but, likely the drying of the regions where they lived lead to habitat loss and their inability to compete with all the new dinosaurs moving into the neighborhood... You'll always be one of my favorite tetrapods, none the less, ole Iron-Face.
