I should have been more clear: I was thinking of the Silica Shale (Caeser Creek, if anyone's interested). In the case I'm thinking of (20k brachiopods at BGSU--I know, because I counded the bloody things!!!) it wasn't MY call--the collecter had classified them, and I was simply recording them. That said, one reason I chose Brachiopoda is that, assuming we're talking Inarticulata, the difference is pretty distinct. Even Inarticulata is fairly obvious, but Inarticulata is as subtle as a war hammer to the skull. We're talking on the level of "If you can't identify this, we're going to take your rock hammer away". In Ohio (Silurian limestone, of various types) the only thing you can possibly confuse a brachiopod with is a bivalve (Phylum Molluska), and if you do that you don't diserve to call yourself a paleontologist. Plus, I can offer my personal assurance (with the assumption that anyone obsessed with the issue can check it out for themselves) that Ohio brachiopods are VERY distinct from bivalves.IanS said:Just as a point of interest - the above is not actually correct anyway.
You are assuming that the visual identification of your samples as “brachiopods” is always correct. However, it’s clearly quite possible that some of the samples may turn out not to have been brachiopods after all.
Yeah, it's a judgement call. But I've never been drunk enough to make that call wrong, and can train a non-expert (specifically, an accountant, an artist, and an EMT) to differentiate between the two in less time than it takes to drink a beer.
The issue is the plane of symetry (I may have butchered the spelling, but after two Johnny Walkers I'm not going to correct it). The easiest way to explain it is with your hands. Put them together. now, separate the left from the right hand. That's the plane of symetry in Bivalvia. Now, put them together again and lift the index finger and thumb away from the middle finger. That's the plane of symetry in Brachiopoda. Again, if you can't differentiate between those two, you don't deserve to call yourself a paleontologist. There's some degree of subjectivity to it, but it's about as minimal as you can get in taxonomy.
rUnderstood. And that's why I picked Brachiopoda--again, Inarticulata is about as far from a subjective judgement as you can get.That is subjective. And does as you put it “ require a judgement call”. They saw what they wanted to see.
...for those that know their Paleozoic invertebrates, I've just given a lot of information about myself.....
That is what skepticism preports to be. However, in practice I've found that they are every bit as biased as others. I invite anyone who doubts me to examine the threads on Objectivism or the Anthropocene to see ample evidence of this. Those people may or may not represent skepticism as you know it, but they are the people carrying your banner.Squeegee Beckenheim said:I consider myself a sceptic simply because I try my hardest to eliminate my own biases and attempt to base my opinions on evidence as much as possible. I certainly don't achieve that all the time, but that's what I aim for. That's all scepticism is, and I find it hard to believe that you don't do either of those things.
I am an Objectivist. There are specific aspects of epistemology that I disagree with regarding the skeptic movement (which does, in my opinion, exist--there are a number of people who agree with certain conclusions and advocate for the consequent social policies, so in every meaningful sense it is a social movement in my opinion [see Dianah Hsieh's essays on the New Atheists to see someone put it better than I currently can]). But regardless, my point still stands: wardenclyffe made a statement that iimplied that all scientsits are sketpics, which I took to mean "are members of the skeptic movement". I'm not a part of that movement, and my views are very different from those that wardenclyffe stated.
