32 vs 30? Is that 32.4 rounded down to 32, or 31.5 rounded up? And 29.5 rounded up to 30, or 30.4 rounded down? Because that’s the difference between a 3.6% size discrepancy and a 9.8% one. For the record, if you have such figures, especially in pixels, never EVER imagine you can pin down the relative sizes to within half a percent using that. And am I getting that right, is dinosauria101 just measuring the sizes of the bones in Hartman’s skeletals with a ruler to confirm what size he scaled them to? Leaving aside the obligatory "Ruler? WTF??", that makes about as much sense as taking someone’s tax return as evidence that they didn’t commit tax evasion. @altrightermeme Calvo & Coria 1998 is a peer-reviewed paper that explicitly states MUCPv-95 to be 8% larger than MUCPv-Ch1. The consensus is that the latter was between 12.2 and 12.5 m, or 12.4 m if we prefer counting only recent skeletal reconstructions. That would put the former specimen at well over 13 m. Now, it is just as unclear how they got that measurement as it is how Hartman got his, but since it is a technical paper, one of whose key conclusions was specifically regarding the size of this specimen, I think it would certainly be fair to say there is a strong possibility it was not just pulled out of thin air. Coria subsequently coauthored the study which all of you are citing for the 2.2% figure, Coria & Currie 2006, so it’s not as if he was unaware of that. This is a figure which we know the basis for, minimum dentary depth being 138 vs 135 mm (which is in fact all the paper says on the matter), but that is not necessarily contradicting the others. Say for example the dentary were 2.2% deeper at the shallowest point, 6.5% deeper at the deepest point, and 15.3% longer along the alveoli, a simple arithmetic mean of those would be exactly 8%. Or say it was 8% deeper at the deepest point and 9.3% longer, then the mean would be exactly 6.5%. I do not know whether a similer methodology is how Calvo & Coria got their figure, though this would be how I would do it, but it is a distinct possibility. Or perhaps their figure refers to the length of a given number of alveoli; that would also make sense, as it is the largest dimension that can be compared and therefore the least sensible to error (being off 1 mm in a ~60cm length measurement is better than being off by 1 mm in a 138 mm depth measurement, obviously). Claims that we know for sure MUCPv-95 was less than 13 m (if that was what you were trying to say) are clearly just as wrong as what dinosauria is doing, so I don’t know what basis there is for such a smug attitude while making them yourself.

There is no such software - I used a ruler. See, this is what drives people endlessly nuts about you. You have all the free time and passion in the world to make your work good, yet you can't be bothered to do so. Seriously - some people would kill to have the amount of spare time you have (I wonder what the profile section would look like if I had the time and passion I had in this forum's infancy). It can't be that you don't care enough for your work. You do, otherwise, you wouldn't share it with us all the time. It can't be a lack of knowledge on what makes good scaling either. According to screenshots I have been shown, people on Discord have castigated you for your misuse of rulers so recently that you can't have forgotten about it by now. My working hypothesis - your narcissism is so great that you can't see problems that are obvious to just about anyone else. And before you respond, do me a favor and come up with something original. Something like "Okay, okay, lesson learned, I won't use a ruler anymore, unless I'm too lazy again (i.e. most of the time)" is predictable. EDIT: Can't tell why, but the tax evasion line made my day. |

I’ll second that. dinosauria101 how about using the lockdown productively and learning how to measure images properly? I think I already gave you all the instructions you need, but I am here should there still be something that’s unclear to you. |

I have pretty much run out of ideas for size comps. Those ones were ones that have already been posted here.

Theropod invited you to practice measuring, not to share every inch of progress you make with us…

I know. But I did run out of ideas, so if I do need the measuring it'll be later

He refuses to take any criticism that is probably why he has moved over to doing what he used to do on here just on Deviant art. He either blocks you or disables comments so you can not point out what he's doing. Such a shame with all that free time and passion he could do great things but because of the clear bias for and against certain animals no one will take the stuff seriously.

When I have more size comps to post, that is. I have nothing ATM.

Post? You can do so in private.

Yes, but I literally can't think of any good ones to make ATM. When I do, I can privately post them.

How very convenient. But besides the point. While it is hard for me to imagine how you could suddenly not have any size comparisons you want to make, after previously posting several each day for months on end and without any regard for whether they had any relevance, you making and posting size comparisons wasn’t what anyone asked you to do.
We suggested you learn to measure things digitally. Doing that would certainly also improve the accuracy of your size comparisons, but the example at hand was your recent attempt at measuring dentaries in (?Hartman’s skeletals of) Giganotosaurus. You can simply retry that, just for practice, no need to make or post any size comparison.

I know this is a few days late but tucking your tail between your legs and running after your posts are called out isn't constructive or helpful to your case. It is mighty convenient you have nothing to post now, as noted, after you had pretty consistently inundated the size comparison thread with your work(s). If you do not want to properly learn, that's fine. But don't blatantly lie about it and/ or make up excuses. |
