$699.99
Name: Tullimonstrum gregarium (Tully Creek Shale (Essex biota)
Location:Mazon Creek, Braidwood, IllinoisSize: Concretion is 5 inches long!
This is a fabulous example of an extremely strange fossil. It is a killer Tullimonstrum gregarium (Tully Monster) from the famous Mazon Creek fauna of Braidwood, Illinois. The Tully Monster was first found by Francis Tully in 1958 - at first, no one could identify the animal, and it was quickly dubbed the \'\'Tully Monster\'\'. Tully monsters are unique to Illinois, and have been designated the official \'\'State Fossil of Illinois\'\'.The Tully Monster was a strange, soft-bodied animal which lived just off shore when the area of Illinois south of Braidwood was a mixture ofmuddy estuaries, marine environments, and rivers and lakes. The Tully was probably an active, swimming carnivore that possessed a long proboscis, an \'\'eye bar\'\' that contained the sensory organs, and a fluked tail. And no one is quite sure if it is a vertebrate or an invertebrate - WOW!
This excellent specimen is missing the end of the proboscis, as are 99.9% of all Tullys ever found. However, the base of the proboscis is well preserved, and the \'\'eye bar\'\' and eyes are VERY easily seen. The long, tubular body is also beautifully preserved. And one of the most exciting features of this fossil is that both halves of the split pair concretion are intact and offered together! This is an extremely collectible example of one of the most enigmatic and localized prehistoric animals ever found, period!
