The Tertiary has been split into the Paleogene and Neogene periods.

Is it fine to portray Leptoceratops qith structures like those of Psittacosaurus, or would it look different ? |

I suppose it's FINE. They were more closely related to more advanced ceratopsians, and the Leptoceratopsids were most closely related to Protoceratopsidae, though actual placement among the ceratopsians is still unclear. I personally wouldn't but there's nothing to suggest they didn't have quills either. |

Thanks for that. Still regarding dinosaur integuments, the skin tracks from Tyrannosaurs show naked skin or small scales ? I've seen different sources stating one of these, and I'm still confused. |

The feet were plated. A bit like the feet of larger groundbirds. Ostriches really. This is simple enough. But based on the rather small fragments we have over a certain distribution, interpretations get a bit muddled up. The integument we have for the underside of the tail for example are small, scale-like features. (If the link doesn't take you to the pic itself, scroll down to page 46 for an example). Of course, it looks scaly. If anything, it looks almost identical to a certain large animal we all know and love. Here's a sample of the skin. And another. Hint: The answer's in the link. Still no clue? Try this. Give up? Ok then. So currently there's a bit of a division between whether the integument was scaly or leather. The problem lies in the fact that despite being photographed and documented, no formal scientific descriptions have been done on ANY tyrannosaur integument.

Thanks again, this gives at least an idea of the texture it had ... |

Would it be okay to still show Ceratopsids with some quills? I'm not talking anything resembling a full coat, but instead just several strands. |

Most likely not for most groups, if anything, give them dermal spines à-la triceratops if you wanna be creative, but bear in mind that even these weren't omnipresent amongst ceratopsids either. (IIRC Chasmosaurus didn't have them and neither did monoclonius, altough iirc the latter could have had a row of spines running down its back from what i heard). i myself am now alternating between spines, simple scaly skin and "armored" osteoderm covered backs for most my ceratopsians.

Any reason to not do so? (that's what I originally meant, sorry that it wasn't clear) |

not other than the large scales pretty much obscuring the hide |

Well for ceratopsids, the normal integument are large round scales surrounded by rosettes of smaller, mosaic-pattern scales. Cladistically speaking, that's the norm - it's seen across BOTH Chasmosaurines AND Centrosaurines. Among the advanced ceratopsians, Triceratops itself seems to be the oddball. That in itself is reason enough to suggest that this was the condition in the common ancestor between both clades. For any ceratopsid to have psittacosaurus-like quills, it'd need to re-evolve them, which is extremely unlikely. |

Yes, but do these impressions come from a significant enough portion of the body to disprove quills all together? |

not all together, but none along the upper back, flanks, or tail |
