All members of the Deinonychosauria were extremly bird-like animals.
Since at least one specimen of each family (if Sinornithosaurus millenii is viewd as member of Dromaeosauridae) has been found with well preserved feather impressions, it is save to say that all Deinonychosauria were adorned with feathers.
Endothermy (warm-bloodedness), although still questioned by a few palaeontologists, was propably another trait common to all members of the group.
The propably most popular known character all Deinonychosauria (and the Troodontidae) shared was an enlarged claw on the second toe of their feet. While this "sickle claw" was inordinatly enlarged in some species, it was just a bit larger then the "normal" claws in others.
Deinonychosauria had (compared to dinosaurs in general) unusual large brains. Their intelligence usually gets rated somewhere between modern birds and small marsupials/mammals!
They were all active hunters and some species were propably able to hunt in packs in order to bring down prey that was much larger then themselves.
Along with all other nonavian-dinosaurs, the Deinonychosauria became extinct during the end of the cretaceous period, 65 million years ago. But one sister-group survived the big catastrophe and has diversified into many forms until today. We see them every day, they live even right in our cities and every other possible habitat our world has to offer: The avian-dinoasurs, better known as birds!
Diese Seiten sind den Deinonychosauria gewidmet. Diese extrem faszinierende Gruppe beinhaltet zwei Gruppen: Die Dromaeosauridae und die kürzlich entdeckten Microraptoria. Darüberhinaus sind auch die Troodontidae bestandteil dieser Seiten, da sie in der klassischen Systematik Mitglieder der Deinonychosauria waren.
Alle Mitglieder der Deinonychosauria ähnelten stark den Vögeln.
Da zumindest ein Fossil aus jeder der drei Familien (wenn man Sinornithosaurus millenii als Mitglied der Dromaeosauridae sieht) mit guterhaltenen Federabdrücken gefunden wurde, kann man ruhig davon ausgehen, daß alle Deinonychosauria mit Federn geschmückt waren.
Endothermie (Warmblütigkeit) war wahrscheinlich eine andere Eigenschaft, die allen Mitgliedern dieser Gruppe eigen war. Dies wird jedoch von einigen wenigen Palaeontologen noch in Frage gestellt.
Das wahrscheinlich allgemein am besten bekannte Merkmal aller Deinonychosauria (und der Troodontidae) war wohl die übergroße Klaue an der zweiten Zehe ihrer Füße. Während diese "Sichelkralle" bei einigen Arten überdimensional vergrößert war, hatte sie bei anderen nur wenig größere Dimensionen als eine "normale" Kralle.
Deinonychosauria verfügten über ein (im Vergleich mit Dinosauriern im allgemeinen) ungewöhnlich großes Gehirn. Im allgemeinen werden sie von der Intelligenz her zwischen modernen Vögeln und kleinen Beutel-/Säugetieren eingestuft!
Sie alle waren aktive Jäger und einige Arten waren wahrscheinlich in der Lage, sich zur Jagd in Rudeln zusammenzuschließen, was ihnen ermöglichte, auch sehr viel größere Tiere, als sie selbst es waren, zu erlegen.
Zusammen mit allen anderen flugunfähigen Dinosauriern starben auch die Deinonychosaurier am Ende der Kreidezeit, vor 65 millionen Jahren, aus. Aber eine Schwestergruppe überlebte die große Katastrophe und hat sich bis heute zu vielen verschiedenen Arten entwickelt. Wir sehen sie jeden Tag, sie leben mitten in unseren Städten und jedem anderen Lebnsraum, den unsere Welt zu bieten hat: Die fliegenden Dinosaurier, besser bekannt als Vögel!
I would like to specially thank Michael Mortimer for allowing me to use the Deinonychosauria part of his Cladogramm on these pages and providing additional info. The copyright for this remarkable (master-!)
piece of cladistic work belongs fully to Michael Mortimer and you can view it in it's full beauty on his "The Theropod Database"-pages (see "Links").
Moreover my special thanks go to Boban Filipovic for providing the marvellous pictures of his reconstructions of Microraptoria and allowing me to display some of them on these pages. The copyright for all those pictures belongs
fully to Boban Filipovic. I think we all can look forward to the completion of his personal website and seeing more of his masterly works!
Another person who deserves special thanks is Scott Hartman for allowing me to use his detailed skeletal reconstructions of dinosaurs and ancient birds in order to illustrate some of the important and more visible similarities
Deinonychosauria share with birds. You can find more of his great works in higher resolution (and thus showing more details) on his website skeletaldrawing.com (see "Links").
Mein spezieller Dank gebührt Michael Mortimer für die Erlaubnis den Deinonychosauria Teil seines Kladogramms auf diesen Seiten zu benutzen und die Versorgung mit zusätzlichen Infos. Die Rechte an dieser kladistischen (Meister-!) Arbeit liegen zur Gänze bei
Michael Mortimer und man kann die Schönheit seines Werkes insgesamt auf seinen "The Theropod Database"-Seiten bewundern (siehe "Links").
Darüberhinaus möchte ich ganz besonders Boban Filipovic dafür danken, daß er mir Bilder seiner wundervollen Reconstructionen der Microraptoria zur Verfügung gestellt, und die Erlaubnis gegeben hat, einige davon auf diesen Seiten zu zeigen.
Ich glaube wir alle können uns auf die Fertigstellung seiner persönlichen Internet-Seiten freuen, auf denen dann mehr seiner meisterlichen Werke zu sehen sein werden!
Eine weitere Person, der ich meinen besonderen Dank aussprechen möchte, ist Scott Hartman für die Erlaubnis seine detaillierten Skelettrekonstruktionen von Dinosauriern und frühen Vögeln benutzen
zu dürfen, um einige der wichtigeren und leichter erkennbareren Ähnlichkeiten zwischen Vögeln und Deinonychosauriern zu illustrieren. Mehr seiner großartigen Arbeiten können in höherer Auflösung (und damit größerem
Detailreichtum) auf seinen skeletaldrawing.com Webseiten bewundert werden (siehe "Links").
Besides, for lending their time to point out the horrible mistakes on the first version of this Site, and discussions: Members of the DinoData Forum: Marcel Opitz, Allosaurus, and Thomas. Members
of the Dinosaurier Interesse Forum: Mironimus Rex, Michael, Webmaster, Hille V., Peter Palzer, Daniel-2, Jens and Trevor Dykes.
Darüberhinaus, dafür, daß sie sich Zeit nahmen die fürchterlichen Fehler in
der ersten Version dieser Seiten aufzuzeigen und mit mir diskutiert haben: Mitglieder des DinoData Forums: Marcel Opitz, Allosaurus, und Thomas. Mitglieder des Dinosaurier Interesse Forums:
Mironimus Rex, Michael, Webmaster, Hille V., Peter Palzer, Daniel-2, Jens and Trevor Dykes.
I also dont want to miss the chance to thank all the scientists mentioned below for their great work (and of course also those not mentioned here!). Although I may not always agree with some of
them, I truly appreciate their continued efforts to broaden our understanding of the world surrounding us today and in the past!
Ich möchte auf gar keinen Fall die Gelegenheit versäumen, all den Wissenschaftlern, die weiter unten erwähnt werden, für ihre großartige Arbeit zu danken (und selbstverständlich auch jenen, die hier keine Erwähnung finden!).
Auch wenn ich mit Einigen nicht immer übereinstimmen mag, so weiß ich doch Ihre fortgesetzten Bemühungen, unser aller Wissen um die Welt die uns heute umgibt und in der Vergangenheit umgab, zu erweitern, sehr zu schätzen!
