Hiodon falcatus?


Roby

Recommended Posts

I found this Green River fish at the American Fossil quarry about 4 years ago. I think it could be a Hiodon falcatus, thoughts?  Thanks for the help!IMG_1468.thumb.JPG.2aef28e671fbefa982ffe2e9c7bca9e9.JPG

It looks like a young Knightia Eocena. This is what a Hiodon falcatus looks like=

Knightia -> dorsal fin in front of body midpoint 
Hiodon -> dorsal fin behind body midpoint.

Thank you. When you don't own an image, you should link to the source of the image, to give them credit for the image. ;)

This comment is directed to everyone, not just to Thecosmila Trichitoma:

 

It's good to get into the habit of giving the source of material (text or photos) that have been produced by someone other than yourself.  The internet makes it easy to appropriate other people's content (even unintentionally or without being aware that this is what you are doing), and web culture treats this as acceptible behavior.  However when you get to University, or try to interact with professional scientists, you will find that this is considered to be plagiarism and is at best grounds for an immediate "F" in a course, and at worst  it may result in expulsion from your program.  It's a bit more work to include sources and/or web links, but it will make your posts more professional, more useful to others who want to delve deeper into the topic you are discussing, and it will prevent a bad habit that could cause professional embarrassment, a bad GPA due to a failed course, or sudden career redirection due to expulsion from your University.

 

If you think this comment is alarmist or an exaggeration, I am a University Professor and I can tell you it is easy to use Google to search the web to see if a student's paper, or any part of it, has been copied from any source that is accessible via the web.  I am aware of several students who have ended up with an "F" because they copied/pasted material.  In one case a Master's student had to do an extensive re-write, still came close to being denied their degree, and had a letter attached to their transcript (and so available to any potential employer who asks for a copy of their transcript) describing their transgression.  All this because the student copied two paragraphs from someone else's thesis.  The student's thesis was over 100 pages, and the two paragraphs were only background information, not actual data or research results, and they still came very close to being kicked out without the Master's degree they had worked on for over two years.

Thanks, I guess wishful thinking.  And thank you moderator for your input.  I will keep that in mind as I go forward.
