Has anyone heard of spontaneous egg division?

I remember reading something about this last summer, that perhaps a frog or some other critter was observed to spontaneously get pregnant without the need for egg fertilization from a male of that species. Anyone else remember the details of this study?

Well it'd be very weird to see a frog get pregnant, as they don't give birth to live young.😛

Some species are able to reproduce asexually, but they are usually simpler creatures; I know that aphids can do that - they can give birth to genetic replicas of themselves.

I think that spontaneous egg division is something completely different - when a fertilized egg splits. Then you get identical twins.

I think this was the entire premise of Jurassic Park. They bred all the dino's female, but since they used frog or lizard or some kinda DNA, it allowed the thing to reproduce asexually. (or something like that)

Now, I realize that was a movie about dinosaurs BUT the lizard/frog/whatever DNA part is true. In a community of all 1 sex, I think some amphibians can do this.

There have been a couple of cases recently involving a snake and a shark, but I think one of those was with sperm stored in the female's body for a few years after copulation.
