Cretaceous wildfires and their impact on the Earth system. – Large numbers of studies on Cretaceous angiosperms have been undertaken over the past 30 years (for a review see: Friis et al., 2006), but the key Early Cretaceous floras containing flowers and reproductive structures contain charcoalified mesofossil assemblages (Friis et al., 2006). Despite these advances, we still have little information on the nature of fire-prone vegetation in the Cretaceous, or on how fire affects, and is affected by, changes in fire systems through the Cretaceous.
Spectacular Fossil Bird Foot Preserved in Amber – Scientific. – Paleontologists owe a debt to. have entirely decayed were split into pieces that stood a better chance of preservation.. we’re going to get to time capsules sent to us from the Cretaceous.
KGS–Geological Log Analysis–The Photoelectric Factor (PeF. – The density porosity reads higher than the neutron porosity curve in this sandstone which reflects the silica content. In general the porosity curves track together, although some "hourglass" patterns pick up small gas effects. The photoelectric factor reads about 2 b/e, which is slightly higher than an anticipated silica value of about 1.8 b/e.
Antarctic Dinosaurs | Britannica.com – Vegavis, an extinct Cretaceous bird collected from Vega Island, was thought to be related to ducks and geese. Polarornis , a loonlike diving bird, was also likely related to an extant bird order. These fossils were considered to be the best evidence that the diversification of modern bird lineages started prior to the end-Cretaceous extinction event, which wiped out all nonavian dinosaurs.
A Possible Hemiphlebiid Damselfly in Late Cretaceous Amber. – The first damselfly in Late Cretaceous amber from South Dakota is described and figured. The specimen preserves the forewing apex of a possible hemiphlebiid, a group of relict damselflies today that were apparently widespread and diverse during the Cretaceous.
