- Palaeontology: A firm step from water to land. Ahlberg, Per Erik; Clack, Jennifer A. // Nature;4/6/2006, Vol. 440 Issue 7085, p747
The article examines the Tiktaalik roseae, a link between fishes and land vertebrates found in Late Devonian river sediments on Ellesmere Island in Nunavut. Tiktaalik is a flattened, superficially crocodile-like animal, with a skull some centimeters in length. The ears and limbs of Tiktaalik...

An introduction to articles on the Siluro-Devonian of Podolia, Ukraine published in this issue of "Acta palaentologica Polonica" is presented.
- Life during the Devonian Period. // Illustrated Guide to Fossil Collecting;1982, p81
An image of species and life during the Devonian Period is presented.
- Palaeontology: First Devonian tetrapod from Asia. Zhu, Min; Ahlberg, Per E.; Zhao, Wenjin; Jia, Liantao // Nature;12/19/2002-12/26/2002, Vol. 420 Issue 6917, p760
The earliest tetrapods (vertebrates with limbs rather than paired fins) date from the Late Devonian Period (370â€“354 million years ago) â€” nine genera have been described, all of which are from the Euramerican supercontinent that comprises Europe, north America and Greenland, apart...
- A hostile land. Flannery, Tim // New Scientist;01/10/98, Vol. 157 Issue 2116, p47
Opinion. Reports on the discovery of a fossil in Australia and relates the finding to that of marsupials. Reference to race disputes over land in Australia; What this discovery signifies; Discussion on the fossil finding.
- Night-stalking marsupials. // Australian Geographic;Oct-Dec2002, Issue 68, p14
Provides information on a national survey of the Australian marsupials and other native animals run jointly by Perth Zoo and the Marsupial Cooperative Research Centre at McQuarie University.
- Marsupial origins in Utah? // BioScience;Feb1994, Vol. 44 Issue 2, p119
Reports on the discovery of a fossil jaw specimen of a species known as Kokopellia juddi that may support the theory that marsupials originated in North America. Features of the fossil; Approximate age of the marsupial specimens from South America.
- Silurian carcinosomatid eurypterids from the Prague Basin (Czech Republic). BUDIL, PETR; MANDA, ŠTĚPÁN; ERIKTETLIE, ODD // Bulletin of Geosciences;2014, Vol. 89 Issue 2, p257
The eurypterid record from the Prague Basin includes occasional Ludlow faunas, but in the uppermost Silurian (PÅ™ÃdolÃ) eurypterids suddenly become common in relatively deep water facies. Pterygotids clearly dominate these late Silurian faunas, whereas carcinosomatids are represented by...
- Comparison of pattern-recognition techniques for classification of Silurian rocks from Lithuania based on geochemical data. Kaminskas, Donatas; Malmgren, Björn A. // Norwegian Journal of Geology / Norsk Geologisk Forening;2004, Vol. 84 Issue 2, p117
There is no widely recognized chemical classification of sedimentary rocks. The geochemical classification of sedimentary rocks utilizes features that can be observed in hand specimens or in thin sections, such as grain size and the mineralogy of the particles and matrix. The main objective...
