Abstract The Hanson Formation of the Central Transantarctic Mountains has
yielded a diverse Early Jurassic terrestrial fauna, which includes the
nearly complete theropod dinosaur, Cryolophosaurus ellioti, and a
fragmentary basal sauropodomorph dinosaur. The Hanson Formation dinosaurs
are important for understanding early dinosaur evolution because: 1) they
preserve a mosaic of morphological traits that render them useful for
interpreting poorly known parts of the dinosaur evolutionary tree; 2) they
are from the Early Jurassic, a critical period in early dinosaur evolution
about which knowledge is scant; and 3) they are the only known Early
Jurassic dinosaurs from Antarctica, making them particularly valuable for
understanding patterns of biotic interchange during this time. Recent
research suggests that Cryolophosaurus belongs to a geographically
widespread clade of mid-sized, Early Jurassic theropods with cranial
crests that includes Dilophosaurus wetherilli, ?Dilophosaurus? sinensis,
and Dracovenator, and renders Coelophysoidea sensu lato non-monophyletic.
The Antarctic sauropodomorph represents a distinct taxon that is a member
of a similarly diverse massospondylid clade. This taxon shares a number of
features with more derived sauropodomorphs, and provides additional
evidence for the paraphyly of Prosauropoda. The phylogenetic relationships
of the Antarctic dinosaurs are also consistent with a pattern of worldwide
faunal homogeneity between Early Jurassic continental biotas. Furthermore,
these analyses support a ?ladder-like? arrangement for basal theropod and
basal sauropodomorph phylogeny, suggesting that these groups passed
through ?coelophysoid? and ?prosauropod? stages of morphological
organization early in their respective evolutionary histories.
The theropod portion of this brief report is coming VERY soon to a major
journal, so I'll talk more about it later. Smith et al. do not name the
clade, but Madsen & Welles' Dilophosauridae would seem to be the most
reasonable version.
The other major paper is:
Butler, R.J., P. Upchurch & D.B. Norman. 2007. The phylogeny of
ornithsichian dinosaurs. Journal of Systematic Palaeontology. early
online edition.
SYNOPSIS Ornithischia is a familiar and diverse clade of dinosaurs whose
global phylogeny has
remained largely unaltered since early cladistic analyses in the mid
1980s. Current understanding of ornithischian evolution is hampered by a
paucity of explicitly numerical phylogenetic analyses that consider the
entire clade. As a result, it is difficult to assess the robustness of
current phylogenetic hypotheses for Ornithischia and the effect that the
addition of new taxa or characters is likely to have on the overall
topology of the clade.
The new phylogenetic analysis presented here incorporates a range of new
basal taxa and characters in an attempt to rigorously test global
ornithischian phylogeny. Parsimony analysis is carried out with 46 taxa
and 221 characters. Although the strict component consensus tree shows
poor resolution in a number of areas, application of reduced consensus
methods provides a well-resolved picture of ornithischian
interrelationships. Surprisingly, Heterodontosauridae is placed as the
most basal group of all well-known ornithischians, phylogenetically
distant from a stem-defined Ornithopoda, creating a topology that is more
congruent with the known ornithischian stratigraphical record. There is no
evidence for a monophyletic ?Fabrosauridae?, and Lesothosaurus (the
best-known ?fabrosaur?) occupies an unusual position as the most basal
member of Thyreophora. Other relationships within Thyreophora remain
largely stable. The primitive thyreophoran Scelidosaurus is the sister
taxon of Eurypoda (stegosaurs and ankylosaurs), rather than a basal
ankylosaur as implied by some previous studies.
The taxonomic content of Ornithopoda differs significantly from previous
analyses and basal
relationships within the clade are weakly supported, requiring further
investigation. ?Hypsilophodontidae? is paraphyletic, with some taxa
(Agilisaurus, Hexinlusaurus, Othnielia) placed outside of Ornithopoda as
non-cerapodans. Ceratopsia and Pachycephalosauria are monophyletic and are
united as Marginocephalia; however, the stability of these clades is
reduced by a number of poorly preserved basal taxa.
This analysis reaffirms much of the currently accepted ornithischian
topology. Nevertheless, instability in the position and content of several
clades (notably Heterodontosauridae and Ornithopoda) indicates that
considerable future work on ornithischian phylogeny is required and causes
problems for several current phylogenetic definitions.

Ĺťywy dinozaur za 10 lat?
Tak na boku to ostatnie badania wykazaĹy, Ĺźe tyranozaur jest doĹÄ bliskim krewnym kury. KiedyĹ ktos poruszyĹ temat, Ĺźe zbadano podobnÄ tkanke miÄkkÄ (tym razem Triceratops) i okazaĹo siÄ, Ĺźe jego kod genetyczny jest identyczny w niecaĹych 70% z indykiem. Otóş chce powiedzieÄ, Ĺźe to caĹkiem moĹźliwe, gdyĹź po pierwsze ptaki ewoluujÄ o wiele wolniej niĹź ssaki, a po drugie to podam pewnÄ zaleĹźnoĹÄ i pokrewieĹstwo:Ĺťywy dinozaur za 10 lat?
- MyĹlÄ, Ĺźe bÄdziemy mieÄ Ĺźywego dinozaura i to wkrĂłtce - w ciÄ gu 5-10 lat - powiedziaĹ prof. Jack Horner z Uniwersytetu Stanowego w Montanie podczas Ĺrodowej konferencji prasowej w Katowicach, gdzie spotkaĹ siÄ z chorym na biaĹaczkÄ chĹopcem - wielbicielem dinozaurĂłw. Horner (na zdjÄciu z gniazdem dinozaurĂłw) jest jednym z najbardziej znanych paleontologĂłw i autorem wielu przeĹomowych odkryÄ dotyczÄ cych dinozaurĂłw.
- 10 lat temu nikt by nie zgadĹ, Ĺźe moĹźemy znaleĹşÄ biaĹko dinozaurĂłw, w tym roku je odkryliĹmy. W nauce nie warto zaczynaÄ od myĹlenia, co warto odkryÄ, ale trzeba byÄ otwartym, mieÄ liberalne spojrzenie i nigdy nie sĹuchaÄ starszych. Zawsze mĂłwiÄ moim studentom, Ĺźe pewnie mylÄ siÄ w wiÄkszoĹci kwestii, ale muszÄ to udowodniÄ - opowiadaĹ paleontolog.
Horner jako pierwszy odkryĹ, Ĺźe dinozaury opiekowaĹy siÄ swoim potomstwem i chowaĹy swoje mĹode w koloniach lÄgowych. Teraz koncentruje siÄ na badaniu róşnorodnoĹci dinozaurĂłw. DoradzaĹ reĹźyserowi Stevenowi Spielbergowi podczas realizacji "Parku Jurajskiego", jego osoba byĹa teĹź ponoÄ czÄĹciowÄ inspiracjÄ dla jednej z gĹĂłwnych postaci filmu, dr. Alana Granta.
PrzykĹadowo czĹowiek (Homo sapiens) dzieli ponad 99,9% materiaĹu genetycznego z neandertalczykiem, 98,4% z szympansem, 95% z gorylem, 70% z psem, 50% z muszkÄ owocowÄ zaĹ 33% z Ĺźonkilem!!!! Dlatego 70% kodu genetycznego w wypadku triceratopsa, ktĂłry zgodny jest z DNA indyka, to Ĺźadne zaskoczenie (jakie panowaĹo w tamtym temacie).
WracajÄ c do tematu to Horner chyba troche przesadza ChociaĹź gwaĹtowny rozwĂłj technologi moĹźe doprowadziÄ do speĹnienia jego wizji

Baryonyx z Portugalii
Eric BUFFETAUT Geol. Mag.: page 1 of 5. 2007 Cambridge University Press doi:10.1017/S0016756807003883
Abstract: Jaw fragments bearing teeth from the Barremian of Boca
do Chapim (Lisboa e Setubal Province, Portugal), originally considered as crocodilian and identified as Suchosaurus girardi by Sauvage, are redescribed and referred to the spinosaurid dinosaur Baryonyx, on the basis of comparison with Baryonyx walkeri, from the Barremian of England. This extends the geographical distribution of this unusual
theropod genus to Portugal. Baryonyx appears to have been a frequent component of Early Cretaceous dinosaur assemblages in the Iberian region,
which may have formed a biogeographical ‘stepping-stone’ for baryonychine dispersal between Europe and Africa.

ABSTRACT: The recovery of material of a small theropod from the Early Maastrichtian, Cape Lamb Member of the Snow Hill Island Formation is an unusual occurrence from primarily marine sediments. The pedal morphology of the specimen that includes a Metatarsal II with a lateral expansion caudal to Metatarsal III, a third metatarsal that is proximally narrow and distally wide, a Metatarsal III with a distal end that is incipiently ginglymoidal and a second pedal digit with sickle-like ungual are all diagnostic of a theropod that belongs to the family of predatory dinosaurs, the Dromaeosauridae. Yet this Antarctic dromaeosaur retains plesiomorphic features in its ankle and foot morphology. As new dromaeosaur species are being recovered from the mid-Cretaceous of South America and the retention of primitive characters in the Antarctic dromaeosaur, a new biogeographic hypothesis on dromaeosaur distribution has been generated. Gondwanan dromaeosaurs are not North America immigrants into South America and Antarctica; rather they are the relicts of a cosmopolitan dromaeosaur distribution, which has been separated by the vicariant break up of Pangea and created an endemic clade of dromaeosaurs in Gondwana.

W Patagonii odkryto dinozaura mierzÄ cego 105 stĂłp
http://news.yahoo.com/s/ap/20071015/ap_ ... EB7g2s0NUERIO DE JANEIRO, Brazil - The skeleton of what is believed to be a new dinosaur species — a 105-foot plant-eater that is among the largest dinosaurs ever found — has been uncovered in Argentina, scientists said Monday.
ADVERTISEMENT
Scientists from Argentina and Brazil said the Patagonian dinosaur appears to represent a previously unknown species of Titanosaur because of the unique structure of its neck. They named it Futalognkosaurus dukei after the Mapuche Indian words for "giant" and "chief," and for Duke Energy Argentina, which helped fund the skeleton's excavation.
"This is one of the biggest in the world and one of the most complete of these giants that exist," said Jorge Calvo, director of paleontology center of National University of Comahue, Argentina, lead author of a study on the dinosaur published in the peer-reviewed Annals of the Brazilian Academy of Sciences.
Scientists said the giant herbivore walked the Earth some 88 million years ago, during the late Cretaceous period.
Since the first bones were found on the banks of Lake Barreales in the Argentine province of Neuquen in 2000, paleontologists have dug up the dinosaur's neck, back region, hips and the first vertebra of its tail.
"I'm pretty certain it's a new species," agreed Peter Mackovicky, associate curator for dinosaurs at Chicago's Field Museum, who was not involved with the discovery. "I've seen some of the remains of Futalognkosaurus and it is truly gigantic."
Calvo said the neck alone must have been 56 feet long, and by studying the vertebrae, they figured the tail probably measured 49 feet. The dinosaur reached over 43 feet tall, and the excavated spinal column alone weighed about 9 tons when excavated.
Patagonia also was home to the other two largest dinosaur skeletons found to date — Argentinosaurus, at around 115 feet long, and Puertasaurus reuili, 115 feet to 131 feet long.
Comparison between the three herbivores, however, is difficult because scientists have only found few vertebrae of Puertasaurus and while the skeleton of Futalognkosaurus (FOO-ta-long-koh-SOHR-us) is fairly complete, scientists have not uncovered any bones from its limbs.
North America's dinosaurs don't even compare, Mackovicky added in a phone interview. "Dinosaurs do get big here, but nothing near the proportions we see in South America."
The site where Futalognkosaurus was found has been a bonanza for paleontologists, yielding more than 1,000 specimens, including 240 fossil plants, 300 teeth and the remains of several other dinosaurs.
"As far as I know, there is no other place in the world where there is such a large and diverse quantity of fossils in such small area. That is truly unique," said Alexander Kellner, a researcher with the Brazilian National Museum and co-author of the dinosaur's scientific description.

Tu jest bĹÄ
d bo mowa tu o szkielecie dinozaura dĹugoĹci 105 stĂłp, czyli 31,5 metra. Wynika na to, Ĺźe nowe bardziej kompletne znalezisko Futalognkosaurus. Odkrywcy sugerujÄ

No tak jakoĹ koĹo 35 metrĂłw ;) Rekonstrykcja tego z Atlanty ( tego ze scenki z Giganotosaurus ) ma pod 37 metrĂłw, jednak ciÄĹźko jest oszacowac pewnÄ dĹugoĹc tego dinozaura, bo materiaĹ kostny na to nie pozwala. DuĹźym znakiem zapytania jest dĹugoĹc jego ogona. Jednak te 35-37 m wydaje siÄ byÄ w miare dobrym szacowaniem. Podobna sprawa jest z Puertasaurus ktĂłry jest znany z bardzo maĹej czÄsci szkieletu, ale zdaje sie on byc powrĂłnywalny lub wiÄkszy niz argentynozaur ( oficjalne oszacowania to 35-40 m ) ;)Danu pisze:Mam wiÄc takie pytanie, ile w koĹcu mierzy Argentinosaurus bo raz mĂłwiÄ , Ĺźe 30 m, raz, Ĺźe 37 m, a niekiedy nawet 45 m
BTW oglÄ daĹ ktoĹ dziĹ Telexpres?? MĂłwili wĹaĹnie o tym. OglÄ dnÄĹem tylko poĹowÄ, ale zdarzyĹem Ĺźeby sĹyszec jak powiedziano ze Futalognkosaurus naleĹźaĹ do tyranozaurĂłw :D
