Sound of Horror (1964 or so)

 

From Wiki- Sound of Horror (Spanish: El sonido de la muerte) is a 1966 Spanish horror film directed by José Antonio Nieves Conde. In the Greek countryside, archaeologists Dr. Pete Asilov and Professor Andre detonate dynamite in an abandoned mountain cave, uncovering petrified eggs in the blasts. Taking one they fail to notice another had hatched, releasing a reptilian creature that vanishes. Andre lives in a nearby villa with his orphaned niece Maria and their superstitious Greek housekeeper Calliope, who warns Andre of the dangers of monsters and angry spirits in the mountain, which he ignores.Back to me:

There is more about this movie on Wiki than I would have thought.  I have seen it once, and since the podcast has been short of dinosaurs this month, it is a good addition.  Good being relative, that is.  I liked it, I think.
