This is the fi rst report of fossil wood with Cedrus anatomical structure from the Cretaceous of Russian Far East, and is the oldest macrofossil evidence of the genus Cedrus. The low diversity. Report on a collection of fossil woods from the Cretaceous of Alberta By D. P. (David Pearce) Penhallow Topics: Alberta, Cretaceous, Paleobotany, Trees, FossilCited by: The wood collection sites span a vertical stratigraphic succession that corresponds to an environmental transect from poorly-drained coastal salt- or brackish water swamps to progressively better drained freshwater flood-plains lying at increasingly greater distance from the shoreline of the inland Cretaceous sea and at higher elevations.

A pellet-filled boring in fossil wood is described from the Early Cretaceous Wessex Formation (Barremian), Isle of Wight. The cylindrical boring, approximately 1cm in diameter, is filled with. 1. Introduction. In Mexico, studies of fossil coniferous woods are few compared to those documented for angiosperm woods. However, in the last 10 years, these have increased since new discoveries of logs or wood fragments in Mesozoic localities in south-central and northern areas of the country have been subject to systematic studies, documenting the plants that produced them, the type of. The collection was reviewed by the Royal Tyrrell Museum and a disposition certificate issued for portions of it that were not considered scientifically significant. This allowed the fossils to leave Alberta. The disposition certificate (#) is on file with the Royal Tyrrell Museum, Drumheller, Rating: % positive.   1. Introduction. Since the first detailed anatomical study of fossil woods from the Antarctic Peninsula and its adjacent islands of Gothan (), fossil woods have been an essential research topic to elucidate the Antarctic paleoflora composition.. Several studies that include fossil woods from the Santa Marta Formation were published in the last decades (Poole and Francis, , .

a fossil Placenticeras meeki from the Upper Cretaceous of Alberta (on display in the Grand Gallery). a large collection of Pliocene-Pleistocene Mollusca (Shugar-Smith collection) from South Florida. a fossil Phragmoteuthis from the Posidonienscheifer Formation of Germany. several fossil Proscorpius osborni from the Upper Silurian of New York. The Hell Creek Formation in Montana overlies the Fox Hills Formation and underlies the Fort Union Formation, and the boundary with the latter occurs near the Cretaceous-Paleogene boundary (K-Pg), which defines the end of the Cretaceous period and has been dated to 66 ± Ma old. The 90 metres ( ft) thickness of the formation is estimated to have been deposited in about 2 million years. Fossil woods are an essential type of fossil for elucidating the ancient canopy forest composition. Systematic studies of Antarctic fossil woods were carried out particularly during the last 20 years (e.g., Poole and Francis, ; Falcon-Lang and Cantrill, ; Poole et al., ; Pujana et al., , ).Their ages range from the Permian (e.g. Maheshwari, ) to the Pliocene (e.g. Fossil material from the Maastrichtian part of the Scollard Formation is identified as belonging to an acanthomorph fish. An articulated specimen, preserved in part and counterpart, is a member of the paracanthopterygian order Percopsiformes, based on it having a full neural spine on the second preural centrum and two epurals in the caudal skeleton (both paracanthopterygian characters), as.
