I would recommend looking at some images.
I don't know for sure, but I would assume Cryptolithus was natant and Eldredgeops was conterminent. Generally conterminent hypostomes are associated with a predatory lifestyle, and Eldredgeops is thought to be predatory while Cryptolithus is not. I would still look it up though (I probably will too).
I would assume the same but I couldn’t find any sources and because Cryptolithus filter-fed with its fenestrae, it might not even have had a hypostome?
