Recreació de l'aspecte a vida de la nova espècie Geiseleptes delfinoi. Imatge: Márton Szábo / Institut Geològic i Geofísic d'Hongria ©Un equip internacional descriu la nova espècie de geco Geiseleptes delfinoi a partir d'un fòssil d'uns 45 milions d'anys d'antiguitat. Les restes van ser trobades en un jaciment alemany el 1933 i demostren la persistència d'aquest grup a Europa des de l'Eocè. La nova espècie seria d'hàbits nocturns com els dragons actuals.

Despite its bird-like appearance, comparative morphology and phylogenetic analyses prove that this genus was a lizard instead of a small avian dinosaur as it was thought when it was first described.
