Mummified Dinosaur?

[CryptoInvestigator]

I posted something previously regarding this episode but perhaps it was misleading. Has anyone ever seen a segment about a Colorado couple horseback riding near the Arizona border where they discovered the body of what looked like a little dinosaur? It was in remarkable condition so I think they were concluding it had been mummified somehow.
Trying to get the names of the individuals involved or at least info on when this was aired.
