[Darryl Pitt]

Perhaps this is the exception that proves the rule, but I've long  
marveled at the distinctively different crust of the EL6 Hvittis  
(witnessed fall - 10/21/1901); it's an articulated stubble which looks  
much like the surface of the spherical sauropod eggshell from South  
America.    /d
