Technically the genus name Pterodactyl is free for use. But the word isn't even a proper scientific name. It's derived from "Ptero-Dactyle", the name given to Pterodactylus by Georges Cuvier in 1809, and is part of the English vernacular. |

To delve a little deeper into the semantics of nomenclature, according to the rules of the ICZN, emending the name Ptero-dactyle to Pterodactylus was technically unjustified, and the correct emendation would have been Pterodactyle. However, since Pterodactylus is the prevailing name and is attributed to the original author, it's considered justified anyway. As for naming a new genus Pterodactyl or Pterodactyle, I'm not really sure how that would work out. There could be some malarkey involving synonyms and stuff, and I'm sure if someone tried to name something Pterodactyle/Pterodactyl there'd be a fuss kicked up and plenty of discussion with the ICZN about it, possibly to find any loopholes to bury the name. Pterodactyle in particular I suspect could possibly be regarded as a nomen oblitum, like Manospondylus, since that's the name originally given (albeit hyphenated). As for Pterodactyl, I'm not sure how that would go down since it's technically a different spelling (think of Centrosaurus and Kentrosaurus), but I wonder if a case could be made about it being an improper latinisation or incorrect grammar or something. I'm sure someone would try those at least. Whatever the case, I can't imagine any attempt to name something Pterodactyl would be an easy feat nomenclaturally, and I personally think it would be more trouble than it's worth. |

Pterodactyl sounds more like a common name for Pterodactylus anyway. |

What would happen if https://en.wikipedia.org/wiki/Velociraptorinae https://en.wikipedia.org/wiki/Alvarezsauridae https://en.wikipedia.org/wiki/Troodontidae https://en.wikipedia.org/wiki/Ornithomimidae Those Dinosaur Groups had survived the Cretaceous/Paleocene mass extinction event alongside the Birds? how different would things go out for the Cenozoic era? |

Not much, really. These four groups are small and specialized enough that Mammals would still have no trouble taking over the world. |

Only difference is that we may have some lines of those non-avian dinosaurs descended from those group living alongside modern animals... Well, if they don't become extinct somewhere during the long peroid of Cenozoic first. |

Well, you'd still see a different set of fauna around by the present day, things wouldn't go exactly the same way except with more dinosaurs still kicking about. Butterfly effect and all that. There's no solid answer to that sort of question, but if I personally were to speculate I'd say maybe you might see velociraptorines getting a head start in the early Palaeocene, since they'd be one of the few (relatively) large terrestrial carnivores left over. Ornithomimids and alverazsaurs are both pretty specialised, so I doubt they'd compete heavily with any of the mammals and could probably continue what they do. Troodontids could possibly be more open to radiating out into vacant niches given their more generalist nature to the other three groups, but I doubt it would be any major setbacks on mammal diversity. Overall, mammals would probably still come to dominate much of the planet with the remaining non-avian dinosaurs beside them. Birds themselves might take a slight hit, some of the flightless niches might be scuppered with other dinosaurs already in similar positions, but that's only a fraction of what they do so birds would be fine as well. /spec |

Well dang, this here makes the complete extinction of all non avian dinosaurs so much more tragic now |

There is the chance that some curotarsans and pterosaurs continuing to make their mark on rising ecosystems as well. Assuming the question is more generalised beyond those four clades. Edited by Incinerox, Sep 11 2016, 03:08 PM.

If the K-Pg was lessened to the degree that those four clades survived, there's no doubt in my mind that other clades would pull through as well. However, I figured sticking to the specific scenario given would just offer a simpler answer. |

how would the general view of Dinosaurs be like if those four groups had survived? how different would things be? |

Under the miraculous, one in a gorillion odds that everything turns out exactly the same, including the evolution and development of our own species and civilisation, I think it would be pretty obvious that we'd have a much better understanding of extinct dinosaurs from the get go. Granted, all four named clades are relatively close to birds, but they each have enough features between them to more immediately link the fossils to the living animals than with birds alone. Long bony tails, teeth, hands with discernible fingers and claws, once more complete fossils would be found the link to modern theropods would be immediate. Things like Archaeopteryx and the fossil beds in Liaoning wouldn't be any great fuss, they'd be pretty much expected. There's all sorts of unpredictable outcomes to this scenario however, these are just some few basic things that come into my head. tl;dr: It would be pretty different. |

so basically, such a alternate timeline would be a far much better place for Dinosaur fans and the Scientific community then the timeline that We live in |
