Researchers said the 18-year-old crocodile who lived alone laid 14 eggs.
DNA from the fetus and the 18-year-old crocodile matched, researchers said, adding that the fetus lacked paternal genes.
In other words, this solidifies the researcher's virgin birth hypothesis.
Warren Booth, an entomologist at Virginia Tech University, told The BBC that virgin births are common in animals that descend from dinosaurs.
He told The BBC that there likely hadn't been a recorded virgin birth among crocodiles before this because most people weren't specifically looking for it.
