Hold on to your butts everyone, because we've got not one but two new species of ceratopsid published in the same day, both in open access to boot. From the Wahweap formation of Diabloceratops fame, we've got Machairoceratops cronusi, which sports an impressive pair of forward curving epoccipitals. ![]() Article: http://westerndigs.org/new-sword-horned-dinosaur-unearthed-in-utah/ Paper: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154403 And after much deliberation, the Judith skull has finally been described and published. Alas, she hasn't revived Ceratops as some had suspected, but her new genus name, Spiclypeus, is a breath of fresh air amongst all the "something-ceratops" we've got kicking about. Reminds me of the likes of Agathaumas or Laelaps. Paper: http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154218 |

Okay, now Machairoceratops is a weird one. |

I agree. Spiclypeus has the better name, though. |

They only have the frill and brow horn yet they are able to determine if it had any nasal horns or not?

Given that it's most closely related to Diabloceratops, Nasutoceratops, Avaceratops and Albertaceratops, which all lack the traditional nasal horn, it can be assumed that Machairoceratops probably lacked a nasal horn as well. |

The brow horns, combined with those large epoccipitals, makes Machairoceratops almost look like it has antlers, when you look at the skull from the side. |

Err... Anyone else thinking that Machairoceratops could easily be just a new specie of Diabloceratops? |

I love how the horns are labeled. "'Oh,' that's a horn." |

Hmm.. Spiclypeus is really interesting. Machairoceratops too, But i think from the shape of the skull I guess it may be an Old Diabloceratops (Maybe an Alpha Male). Both species looks much |

I would not be surprised if this just turns out to be new Diabloceratops material. |

To quote the relevant portions of the paper:
So at the very least they've provided justification for naming it a distinct genus, which may or may not satisfy you depending where you sit on the lumper-splitter spectrum. |
