I recently reported that Scientific American had posted some misinformation about the extinct equid Hyracotherium (Eohippus) on their website and have since received a short e-mail from Katherine Harmon―author of the slide show which drew my ire―thanking me for catching the mistake and informing me that she had changed the entry.
When I checked it out I found that not only had she removed the inaccurate information about Richard Owen thinking that Hyracotherium had been some sort of hyrax but she put in an asterisk and footnote stating that the correction had been made! So she not only corrected the mistake but owned having made it by noting the correction rather than simply flushing it down the memory hole.
Well done Ms. Harmon; much respect!
Now I have to start seriously thinking about changing the darn Wikipedia entry that caused the confusion in the first place…
