* All the animals in ''VideoGame/{{Parkasaurus}}'' hatch from eggs, including the fully-aquatic reptiles, who gave [[PregnantReptile live birth]] in real life.

* ''Series/PrehistoricPlanet'' features the ''Adalatherium'', a badger-like Mesozoic mammal. It's first introduced inspecting a clutch of eggs in a burrow, [[BaitAndSwitch with the narration that it is raiding a dinosaur nest]] as early mammals are stereotyped to do, but as it turns out...''they are her own eggs.''[[labelnote:note]] ''Adelatherium'', like most non-eutherian Mesozoic mammals, were egg-layers. Egg-laying used to be far more common in Mesozoic mammals.[[/labelnote]]

* In one episode of ''WesternAnimation/DinosaurTrain'', Mr. ''Pteranodon'', Tiny, Buddy, and Cindy ''Cimolestes'' met an amphibious mammal called ''Castorocauda''. Cindy (who's a stem-placental mammal) is so shocked to see baby ''Castorocauda''s hatch from eggs that she almost faints.

* In one episode of ''WesternAnimation/DinosaurTrain'', Mr. ''Pteranodon'', Tiny, Buddy, and Cindy ''[[MeekMesozoicMammal Cimolestes]]'' met an amphibious mammal called ''Castorocauda''. Cindy (who's an early placental mammal) is so shocked to see baby ''Castorocauda''s hatch from eggs that she almost faints.

* Occasionally, a chicken might have trouble laying an egg. Instead of going down the oviduct and out the cloaca like normal, it might remain there. Another yolk comes down for the eggshell to form and it might encase the previous egg as well, resulting in what looks like a larger then normal egg once the chicken finally lays it. This large egg will have the previous egg inside it. Other times, an egg will come out with a shell and white, but no yolk, and such eggs were once thought to be laid by ''roosters''. Still other times, if a hen has some kind of distress or illness, she might lay a "cooked" egg or a mass of congealed pus. (No, really.) Most of the time, though, she will either lay sporadically or stop laying all together after that.

* ''VideoGame/{{Bomberman}}'': Blowing up a soft block in later games will sometimes yield a giant egg. Touch this egg, and an [[RidiculouslyCuteCritter adorable]] ''[[KangaroosRepresentAustralia kangaroo]]'' hatches. ({{Averted|Trope}} in ''Saturn Bomberman'', because they're [[EverythingsBetterWithDinosaurs dinosaur]] eggs instead.)

* Beluga caviar sounds like this trope, but [[NamesTheSame it's actually eggs from a fish called the Beluga Sturgeon.]][[note]]The word "beluga" comes from a Russian word meaning "white", so it's not terribly surprising that it appears in the names of unrelated species.[[/note]]

* When Mary asks Max how babies are made in ''WesternAnimation/MaryAndMax'' he says his mother told him that babies hatch from eggs layed by a rabbi.

* In ''Film/SuperMarioBros'', Daisy hatches from an egg. [[HumanAliens Despite appearances]], she's the child of a [[BeastMan dinosaur-person]] and the dinosaur-people are still oviparous.

* Happens as a (disturbing) twist at the end of the ''Literature/{{Goosebumps}}'' book ''Literature/EggMonstersFromMars''. The protagonist, a 12-year-old boy, was impregnated by the titular monster and lays an egg in the last page.

* Here's some weirdness for ya. A good portion of mammalian DNA is non-sequencing, or "junk" DNA. That doesn't mean it doesn't do anything, though. For example, some of that is very important in allowing a fertilized egg to attach itself to the uterus. Some of that comes from [[http://en.wikipedia.org/wiki/Endogenous_retrovirus Endogenous Retroviruses]] which basically means that an ancestor was infected with a virus that incorporated itself into their genetic code and passed it on to all future generations. Putting all that together has led scientists to theorize that it was a viral infection that allowed modern fetuses to bypass the mother's immune system and necessitate live births as opposed to eggs, splitting reptiles and mammals.

* The EasterBunny, according to some. They're not all chocolate, you know. Mythologically, the bunny [[BalefulPolymorph originated as an egg-laying animal]]; being able to lay eggs once a year was a form of consolation (the day was only later {{retcon}}ned to Easter). Of course, in the original myths the bunny wasn't [[ShesAManInJapan Peter Cottontail]]. While most modern versions of the character don't actually produce the eggs from their own body, this hasn't stopped the tradition from confusing kids for centuries anyway.

* ''Series/That70sShow'': In "Hyde's Birthday", [[TheDitz Kelso]] sneaks into the Formans' garage to get a saw, and when he gets caught by Red, [[BadLiar and that goes about as well as you'd expect]], leading to this amazing line:

->'''Lisa''': Wait. Rhinos don't come from eggs.
->'''Homer''': What did you just see, Lisa?
->'''Lisa''': I know, but-
->'''Homer''': ''What did you just see?''
->'''Lisa''': Hmph.

** The Jackai are race of [[{{Hobbits}} hobbit]] sized humanoids that somewhat resemble a cross between a cat, ferret and rodent but they lay eggs in communal hatcheries.[[labelnote:fun fact]] The comic's creator based the jackai child rearing method off that of the titular creatures from the show ''WesternAnimation/{{Gargoyles}}'' of which she is a fan.

* Tsetse flies. They even raise their larva on a bug analogue of milk while they are developing.

* In Myth/ClassicalMythology, Leda, the human queen of Sparta, has sex with Zeus in the form of a swan, and later with her human husband Tyndareus. She lays two eggs, one containing Castor (usually the son of Tyndareus) and Polydeuces (son of Zeus), the other containing Helen (usually daughter of Zeus), later of Troy, and Clytemnestra (daughter of Tyndareus). The parentage and pairing of these children is not consistent, but the story always involves two completely normal human children hatching from eggs.
