Quick, new refs

[Ralph Chapman <MNHAD002@SIVM.SI.EDU>]

 Some new refs with lots more to come soon.

 In the 18Aug95 issue of science there is a report on latest Ancient DNA
 conference (I got to go to the one here a few years ago - it was fun!)

 Williams, Nigel. 1995. The trials and tribulations of cracking the
    Prehistoric code. Science 269:923-924.

 They seem to be arguing more hotly than ever about whether anything over
 100,000 years is any good. This should be interesting.

 Then Walter Alvarez and crew have a long and interesting paper  about
 Chicxulub and why a warm accelerating fireball should solve 3 major problems
 with the impact data - that some shocked quartz in N. Amer. occurs above
 the boundary, why it's more abundant West than East, and how it could
 withstand initial velocities that should have melted it.

 Alvarez, W., P. Claeys & S.W. Kiefer. 1995. Emplacement of Cretaceous -
   Tertiary Boundary Shocked Quartz from Chicxulub Crater. Science 269:930-935.

 Interesting....

 And finally for now (more coming...)

 Cook, E. 1995. Taphonomy of two non-marine Lower Cretaceous bone
    accumulations from southeastern England. Palaeo, Palaeo, Palaeo
    sorry thats Palaeogeography, Palaeoclimatology, Palaeoecology
    116:263-270.

 Two Wealden outcrops are very different in their taphonomy as indicated by
 their dinosaur and other bone materials. One appears to be a fluvial high-
 energy lag (lots o' abrasion) and the other a low-energy overbank
 deposit with less abrasion but more subaerial weathering. Neato for us
 taphonomy freaks.

 More to come, Your pal, Ralph Chapman, NMNH

 The question of the week is "Will the US Gov't shut down on Oct. 1?"
 or put another way, "Is the USA really a third world power?"
