1. Tafolara Neógena da Formação Pindamonhangaba, bacia de taubaté, em Jacareí, estado de São Paulo Brasil. / Tafolara Neógena Training Pindamonhangaba bowl taubaté in Jacarei, São Paulo Brazil.
This work presents a paleobotanical analysis of a Neogene taphoflora of the Pindamonhangaba Formation, localized in the City of Jacareí (SP), based on the morphographic, taxonomic and taphonomic aspects looking for information on paleoenvironment, paleoclimate and paleophytogeographic conditions under which the original flora was submitted. The taphoflorist

2. Licofitas Guadalupianas da Bacia do Parana : Novos dados morfo-anatomicos / Guadalupian lycopos from the Parana Basin : new mopho-anatomic data
Lycopodiopsis derbyi é a espécie à qual mais comumente se relacionam os fragmentos caulinares licofíticos encontrados em estratos guadalupianos da Bacia do Paraná. Tipicamente caracteriza-se por um cilindro vascular sifonostélico com o anel descontínuo cortado por raios medulares e pela presença de almofadas foliares rômbicas com vesícula infrafoli

3. Early Creatceous gymnosperms from the Crato Formation, Araripe Basin, Northeast Brazil / Gimnospermas eocretáceas da Formação Crato, bacia do Araripe, Nordeste do Brasil
Crato Formation, located in the Araripe Basin, Northeastern Brazil, bears one of the most important Lower Cretaceous fóssil plant Record. The fossils have an excellent preservation, usually low fragmentated, with attached organs and epidermic and anatomic features delicatedly replaced by iron oxides. As it happens worldwide, gymnosperms were the dominant gr

4. Tafoflora deógena de depósitos provavelmente correlatos à formação Rio Claro, ocorrente no Município de Jaguariúna, SP
The Jaguariúna taphoflora occurs in Cenozoic sediment probably correlated or included in the Rio Claro Formation, outcropping at the left margin of the km 136,5 of the highway SP-340 (from Campinas to Mogi Mirim direction). This taphoflora is preserved as foliar impressions (parts and counterparts) covered by whitish film, on a massive variegated yellow-ora

5. Toward a new synthesis: Major evolutionary trends in the angiosperm fossil record
Angiosperm paleobotany has widened its horizons, incorporated new techniques, developed new databases, and accepted new questions that can now focus on the evolution of the group. The fossil record of early flowering plants is now playing an active role in addressing questions of angiosperm phylogeny, angiosperm origins, and angiosperm radiations. Three

6. Earth history at the century mark of the U.S. Geological Survey*
Earth history involves all aspects of geological and biological evolution, especially paleontology and stratigraphy. Early paleontological exploration of the western United States by and before the U.S. Geological Survey featured the dramatic discoveries and rivalries of the great vertebrate paleontologists Leidy, Cope, Marsh, and Osborn. Invertebrate paleon

7. Plant biology in the future
In the beginning of modern plant biology, plant biologists followed a simple model for their science. This model included important branches of plant biology known then. Of course, plants had to be identified and classified first. Thus, there was much work on taxonomy, genetics, and physiology. Ecology and evolution were approached implicitly, rather th
