Biology Letters
In a report published in "Biology Letters", researchers reveal the first-known case of facultative parthenogenesis or a "virgin birth" in a crocodile, where a female American crocodile living in isolation at a Costa Rican zoo laid an egg of a fully formed stillborn crocodile that exhibited parthenogenesis. Researchers suggest that the findings could provide insights into the reproduction of crocodile ancestors, including dinosaurs and pterosaurs.
