before you ninja'd me earlier when you restated what you had meant ![]() what I meant was you had said endothermy appeared to have evolved alongside powered flight in pterosaurs, and you said the same appeared true of birds implying that terrestrial dinosaurs were not endothermic you later restated that to less active dinosaurs, but I was ninja'd while I posted that so I was a few posts behind |

Hi everyone. I was looking up some information on dinosaurs when this question occurred to me: are there any official terms for young, adult male, and adult female dinosaurs? Several places will refer to an adult male as a bull while others will refer to young as hatchlings. Do we know what the official terms are or can they be whichever seems more correct (albeit still being reasonable) by analogy? Also, would these terms differ between different groups of dinosaurs such as theropods and sauropods, etc.? Thanks for the time and I appreciate any responses! |

The easiest way is: Hatchling -> Young -> Juvenile -> Subadult -> Adult -> Old Depending on perspective, some herbivores like ornithopods can be called after bovids (calf, cow, bull) while I personally like to call ceratopsians after pigs - sow and boar. It's a bit messy, so it's best to cling to the usual combo I wrote above

Plus, most modern baby theropods are called chicks, so chicks could be used for extinct theropods too

What is the Supportive and Unsupportive arguments for Feathers and Quills (and possibly Pycnofibers) being Homologous structures?

walkeri is from Alberta where tubicen hails from New Mexico, tubicen is also known for more complex airways, and is the largest of the three species. |

P. tubicen also has a slightly longer crest IIRC. |

I don't recall anything concrete on that regard but it does seem like a safe bet there is a common ancestor for all |

Thank you MrGorsh and Okeanos for those responses, its appreciated. Pig terms do seem to fit the ceratopsians quite well and calling baby theropods chicks feels right and makes sense (especially with modern relatives). While Parasaurolophus was being mentioned, I did some research on its Asian relative Charonosaurus and was wondering if anyone knows for certain what its length and weight are? I'm asking because its size seems to vary from source to source, some claim a length of 10 meters while others say it was about 13 meters. Edited by SamtheMan, Jul 1 2014, 04:15 AM.

Charonosaurus is larger than Para, I guess the 13 metres is more correct. |
