To add fuel to this -
The famous NZ physicist Rutherford once quipped:
Theres two types of science: physics, and stamp collecting
The more I read the geological and biological journals the more I think hes right..
I agree theres an art or craft to any identification, and theres always a battle between the lumpers and the splitters: I have a similar, if not greater, problem identifying palaeontological samples. What was it exactly that cheezed you off?
BTW: When I was a wide eyed enthusiastic 16 year old I wanted to be a marine biologist when I grew up so I was thrilled to get 4 weeks work experience at the Antarctic Centre: but I spent every single day sorting krill by age and sex and I can still, 20 years later, smell the formaldehyde. This was a formative event in my becoming a geologist.
