Hey all! 

 

I found a hunk of Isotelus! Found in Fort Mitchell, KY this last weekend. I am wondering if this is actually a fragment of an Isotelus Rex?!

 

Let me know your thoughts. It's been a bit since I posted on the website and I'll be sharing over a years worth of hunting soon!!!! 

 

All the best,

 

Steve

Awesome find! I don't however think its part of an Isotelus rex, they grew up to over 28 inches long and your piece is about 4 - 5 inches (Guessing) which would have made the complete one around 12 inches long. This size I estimated is an educated guess so I wouldn't be surprised if I was off by a few inches but it wouldn't be a foot difference. Isotelus rex or not still a cool piece

I tried comparing it to a full size isotelus although it doesn't line up too well so you need to multiply the length of your piece by about 2.7 to get the full length,

I think the inserted picture needs to be flipped 180 degrees and moved to the bottom left, nice specimen btw

I agree with Phevo, you can see from the direction of the pluera that this is from the left side of the trilo and contains part of the pygidium.

Isotelus rex has only been reported from Manitoba, Canada.  Large specimens of Isotelus maximus measure up to 16 inches (41 cm) in length.

Thanks, I wasn't sure if it was part of the pygidium or cephalon, figured I had a 50% chance of getting right.
