RE: new site bearing dinosaur remains found in Brazil
Since online translators such as Babelfish, despite how well they are
constructed, tend to give quite crappy translations here is the analogical
Geologist Finds Dinosaur "Mine" In The Brazillian Northeast
Thanks to a tremendous stroke of luck, Rio Grande do Norte and Rio do
Janeiro researchers stumbled upon a 3 kilometer area littered with dinosaur
fossils in that northeastern state [Rio Grande do Norte, just a little
further south along the coast from the Amazon delta]
It's the first record of the pre-historic megarreptiles[sic] in the region,
and the preliminary analysis is revealing at least three diferent types of
herbivores and carnivores, besides crocodiles and fish.
"It isn't needed for one to be a paleontologist to wonder about unknown
species as the material is very abundant" said Francisco Pinheiro Lima Filho
from the Universidade Federal do Rio Grande do Norte(UFRN).
Teaming up with co-workers from the Universidade Federal do Rio de Janeiro
(UFRJ), the Universidade Estadual do Rio Grande do Norte (UERN) and the
Universidade Estadual do Norte Fluminense (UENF), he took part on a field
trip that identified the dino graveyard just 15 days ago.
Lima Filho was interested in going to the site for two years after he
visited the area to do a geological survey supported by Petrobras [the
national petroleum company of Brazil]. During that field trip they spotted a
large vertebra but didn't think much of it as Rio Grande do Norte is known
for other megafaunal remains such as of ground sloths and mastodons [?!?
Mastodons in South America?].
The geologist presented the vertebra to an ex-student of his, the
paleontologist Maria Fátima dos Santos, from the UFRN Câmara Cascudo Museum.
A quick look was all that was needed to confrim the dinosaurian nature of
"At that time" the researcher muses "a small light turned on". Lacking was
the funding needed to get specialist to go to the site for which Lima Filho
had to wait until the beginning of this year.
As the place where the vertebra was collected was registered with a GPS
device there was no difficulty in finding the site and for the geologist to
re-examine it with the help of paleontologist Lilian Paglarelli Bergqvist
from the UFRJ and other researchers.
The vertebra had rolled down from its original location but it wasn't
difficult to find much bigger fossils, including 1,5-meter femurs. Some
fossils were still enclosed in the matrix and the team quickly found a great
variety of teeth, which are a good indicator of the group the animal
sporting them belonged to.
Refering to the teeth and the femurs, Carlos Roberto dos Anjos Candeiro,
doctorate student of Bergqvist in UFRJ identified at least three types of
dinos from the Potiguar Basin Formation [done a bit of editing to make this
a bit more comprehensible] carcharodontosaurids, abelisaurids and
One of the last brazillian dinosaurs to be described was Amazonsaurus
maranhensis, measuring 10 m in length was a diplodocoid. The faunal
assemblage is similar to the one found in Africa, continent that maintained
conections with South America at that time.
The fossil-bearing strata belong to the Potiguar Basin Fm. dating from the
Cenomanian, some 90 million years ago. The area at that time was a large
estuary [large river-mouth in literal translation].
The researchers are seeking Petrobras's support in the detailed study of the
fossil beds. While the funding isn't available the exact location of the
fossil site is going to be kept secret to avoid the same wrong-doings done
in the Araripe [remember Irritator challengeri?].
To paleontologist Carlos Roberto Candeiro, the fossils found in the site
suggest that the Brazillian and African faunas still maintained contact
despite the big separation between Africa an South America at that time.
"Material from Maranhão, which is almost co-eval, also shows those
similarities to Africa" states Candeiro. An example of it is the presence of
carcharodontosaurids, common in regions such as Morrocco. According to the
researcher one can expect more new species from this site.
I think it keeps to the original intent of the text though I've upgraded the
reading level a bit since I think most people here can understand the
jargon. Anyway I apologize for any spelling mistakes or grammatic blunders,
but this took quite a while to make and I just can't bother to spell check.
