This fossil was inherited so unfortunatly I don't know the background on it. The creature within is approximatly three inches in length. It appears to have skin like an alligator with the tail of a fish, most resembling a coelocanth tail. My interest in the fossil was renewed after reading about the discovery of tiktaalik. Unlike other supposedly pre-tetrapod fishes, there is no sign of any anterior fins (besides caudal) or appendages. This has given pause to some professional paleontologists who will not even hazzard a guess as to whether what I have is, as I believe, even a vertibrate. (I can't help but wonder if it may be some sort of transitional species, possibly even one with growth stages likened to a modern amphibian.) The previous owner of this fossil was a long-time resident of Corpus Christi, Texas. He also once lived near Fayetteville Arkansas. My suspicion is that the fossil is from the Nueces River Basin. GoodLuck.
