Да, яки са тези тероподи. Живото доказателство, че кархародонтозавридите имат меко казано странни представители.

Наистина странно животно юрски теропод с пера.Но също така невероятно добре изглеждащо.

Странното не е това, че е възможно да има пернати динозаври от юрата (Archaeopteryx, Pedopenna и Anchiornis са късно юрски динозаври и имат съвременен тип пера, което означава, че тези структури са възникнали много по-рано, вероятно още при първите целурозаври през средната или ранната юра), а това, че има индикации за присъствието на предшественик на перата при кархародонтозаврид, което означава, че перата са възникнали много по-рано в еволюцията на тероподите и обхващат една по-широка тероподна клада, а не единствено Coelurosauria. Много палеонтолози обаче смятат, че структурите открити по лакътната кост на Concavenator, които са интерпретирани като зони за захващане на пера, всъщност са отпечатъци от захващането на някои от сухожилията на ръката. И за момента изглежда, че са прави в това си предположение. Това, което съм нарисувал не са истински пера, а по-скоро кератинови структури предшественици на протоперата, които пък са предшественици на съвременните типове пера.

Thanks.

Concavenator is primitive carcharodontosaurid. I have nice cladogram which is showing the exact place of this animals in Carcharodontosauridae but unfortunately it's on another computer. Try to google it. Here is the wikipedia's article - [link] .

only one thing, didn't this guy only have bumps for 5 quills?

I don't know... I didn't read much about this guy except for the first articles which appeared in JPL. Anyway, I think the number of quills is not directly related to the number of quill knobs, like the case with dromaeosaurids and birds. The presence of quill knobs is a 100% proof for a presence of feather but their lack doesn't mean absence doesn't mean lack of feathers. I suppose same goes for quill like structures. Even if Concavenator had only 5 quill knobs in my opinion this deosn't mean it didn't have larger number of quills. I followed this logic, although it could be flawed. I just had not chance to make research on the subject.

I will! ;)

Please excuse the bad spelling in my previous post. I typed it pretty fast and posted it without editing by an accident.

Here is link to the Velociraptor quill knobs paper -> [link] . See this citation - "Quill knobs are variably present in extant bird species and are present in only a few basal taxa such as Ichthyornis (2), so their absence does not necessarily indicate a lack of feathers. Their presence, however, is a direct indicator of feathers of modern aspect (e.g., feathers composed of a rachis and vanes formed by barbs).". I guess the same could be apllied to Concavenator's quills.
