In 2009, approximately 44 new non-avian dinosaur genera* were named from fossils around the world** These are as follows:

01. Adeopapposaurus (Sauropodomorpha; Massospondylidae)
02. Aerosteon (Theropoda; Neovenatoridae)
03. Albalophosaurus (Cerapoda incertae sedis)
04. Anchiornis (Theropoda; Troodontidae)
05. Angulomastacator (Hadrosauridae; Lambeosaurinae)
06. Arenysaurus (Hadrosauridae; Lambeosaurinae)
07. Australovenator (Theropoda; Neovenatoridae)
08. Baotianmansaurus (Sauropodomorpha; Macronaria)
09. Barrosasaurus (Sauropodomorpha; Titanosauria)
10. Beishanlong (Theropoda; Ornithomimosauria)
11. Ceratonykus (Theropoda; Alvarezsauridae)
12. "Coahuilaceratops" (Cerapoda; Ceratopisa)
13. Diamantinasaurus (Sauropodomorpha; Titanosauria)
14. Elrhazosaurus (Iguanodontia; Dryosauridae: new designation for Valdosaurus nigeriensis).
15. Helioceratops (Cerapoda; Ceratopsia)
16. Hesperonychus (Theropoda; Dromaeosauridae)
17. Kemkemia (Theropoda incertae sedis)
18. Kinnareemimus (Theropoda; Ornithomimosauria)
19. Kol (Theropoda; Alvarezsauridae)
20. Leshansaurus (Theropoda; Sinraptoridae)
21. Levnesovia (Iguanodontia; Hadrosauroidea)
22. Limusaurus (Theropoda; Ceratosauria)
23. Malarguesaurus (Sauropodomorpha; Titanosauria)
24. Minotaurasaurus (Ankylosauria; Ankylosauridae)
25. Miragaia (Thyreophora; Stegosauridae)
26. Owenodon (Ornithopoda; Iquandodontia: new designation for Iguanodon hoggi)
27. Panphagia (Saurischia; Sauropodomorpha)
28. Qiaowanlong (Sauropodomorpha; Brachiosauridae)
29. Raptorex (Theropoda; Tyrannosauroidea)
30. Ruyangosaurus (Sauropodomorpha; ?Titanosauria)
31. Shaochilong (Theropoda; Carcharodontosauridae)
32. Shidaisaurus (Theropoda; Tetanurae)
33. Sinotyrannus (Theropoda; Tyrannosauroidea)
34. Spinophorosaurus (Sauropodomorpha; Sauropoda)
35. Skorpiovenator (Theropoda; Carnotaurinae)
36. Tatankacephalus (Ankylosauria; Ankylosauridae)
37. Tawa (basal Theropoda)
38. Tethyshadros (Ornithopoda; Hadrosauroidea)
39. Tianyulong (Ornithischia; Heterodontosauridae)
40. Tianyuraptor (Theropoda; Dromaeosauridae)
41. Wintonotitan (Sauropoda; Titanosauria)
42. Xinghesaurus***
43. Xiongguanlong (Theropoda; Tyrannosauroidea)
44. Zanabazar (Theropoda; Troodontidae)

Even if 10-20% of these taxa should ultimately be judged to be invalid (for whatever reason), that's still a very good year for dinosaurs.

Oh, and behind the cut, Nobu Tamura's "2009 in Paleontology":







*I've not included new species named to preexisting genera, or this list would be a bit longer.
**Olshevsky, George. "Dinogeorge's Dinosaur Genera List"
*** Invalid taxon

Thanks for the information. Makes sense. My background is in molecular biology, so back when I did this sort of thing the way I looked at relatedness was, of course, by DNA sequence (or maybe protein sequences).

I've always been impressed and somewhat amazed by the ability of paleontologists to distinguish fossils based on what appears (to my untrained eye) to sometimes be barely perceptible differences.
