Steve D. Posted November 10, 2020 Share Posted November 10, 2020 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 5 Link to comment Share on other sites More sharing options...
Top Trilo Posted November 10, 2020 Share Posted November 10, 2020 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.

Top Trilo Posted November 10, 2020 Share Posted November 10, 2020 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, 1 “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.
