TI Cretaceous-Tertiary (Chicxulub) impact angle and its consequences
AB The Chicxulub impact structure exhibits asymmetries in its geophysical
signatures that closely resemble asymmetries produced by oblique impacts in
laboratory experiments and recognized on planetary surfaces, These
asymmetric signatures suggest a trajectory for the Chicxulub bolide from
the southeast to the northwest at a 20 degrees-30 degrees angle from the
horizontal. As a result, biotic extinctions may have been most severe and
catastrophic in the Northern Hemisphere, Geographic variation in the
magnitude of the Cretaceous-Tertiary (K-T) ''fern spike'' and palynofloral
extinctions are consistent with the proposed trajectory.

TI Dinosaur bones: fossils or pseudomorphs? The pitfalls of physiology
reconstruction from apatitic fossils
AB A prerequisite to any attempt to reconstruct thermophysiology of ancient
animals through analysis of stable isotopes of oxygen is the assumption
that apatitic fossils are isotopically unaltered parts of their original
skeletons. We suggest that sufficient evidence is available to seriously
question this assumption. Because living bones contain about 1/3 by weight
of organic matrix, mass balance considerations show that at least half of
an apatitic fossil must be new material added post mortem. Furthermore,
living apatitic skeletons contain almost no rare earth elements and
uranium, whereas apatitic fossils bear high concentrations of these
elements. Additionally we found that while in living fish correlation
between delta(18)O of oxygen in the phosphate and that in the carbonate of
apatite is poor, these two values are linearly correlated in fossil fish.
This suggests diagenetic recrystallization has taken place. Perfect
preservation of micro-textures such as Haversian canals does not prove the
pristine condition of a fossil; some of the most beautifully preserved
fossils are highly silicified. Most apatitic fossils probably are
pseudomorphs replacing original skeletal elements. Whereas distribution of
stable isotopes of oxygen in fossils might provide information about their
burial environment, it could be misleading in attempts to interpret the
organisms' physiology. This cautionary note is supported by the similarity
of delta(18)O(p) in bones of coexisting fossil fish, dinosaurs, and various
other reptiles at different latitudes. The overlap of predicted
delta(18)O(p) values in fish and mammals living in contact with the same
environmental water also weakens the hope that ectotherms can be
distinguished from endotherms by the isotopic composition of oxygen in
their bones and teeth.
