Then there are its eyes, which protrude outward from its body on stalks. He took the strange creature to the Field Museum of Natural History, but paleontologists were stumped as to which phylum Tullimonstrum belonged. Dense swamps were pierced by meandering, muddy rivers full of animals like the early relatives of jellyfish and shrimp.

A typical fossil of a Tully Monster. Since 1989, the Tully monster has been the official state fossil of Illinois. Firstly, it was noted that even the presence of the two melanosome types is variable among vertebrates; hagfish lack them altogether, and extant sharks as well as extinct forms found in the Mazon Creek area, such as Bandringa, only have spheroid melanosomes. The "mouth" at the front of the proboscis was described as possessing gnathostome-like distinct tooth rows, despite lampreys having "tooth fields" on the interior of the mouth. Coastal Fossils: Agatized Coral Fossil, Bivalve Fossil, Brachiopod Fossil, Common Petrified Wood Fossil, Cephalopod Fossil, Petoskey Stone Fossil, Neospirifer Fossil.

The mechanisms of preservation in the Mazon Creek are poorly understood. Official State Fossil of Illinois The Tully monster (Tullimonstrum gregarium) was designated the official state fossil of Illinois in 1989. [2][4] Tullimonstrum possessed structures which have been interpreted as gills, and a possible notochord or rudimentary spinal cord.[1][5].

You can unsubscribe at any time and we'll never share your details to third parties. Chen et al. These fossils are unique because of the chance that soft tissue shapes have been preserved, often with many fine details. The reasons are unclear... maybe it's the strange shape of the animal, … But our research demonstrates how studying fossils at the chemical and molecular levels can play an important part in figuring out the identity of this and other enigmatic creature.

Mikulic, Illinois State Geological Survey, and J. Kluessendorf , University of Illinois Department of Geology. We also found that Tully's eyes contain different type of copper to that found in vertebrate eyes. Meanwhile, the gill pouches of lampreys are paired extensions rather than segmented structures, and are usually embedded in a complex gill skeleton, neither of which is the case in Tullimonstrum. [1] This affinity was attributed based on pronounced cartilaginous arcualia, a dorsal fin and asymmetric caudal fin, keratinous teeth, a single nostril, and tectal cartilages like in lampreys. When excited, each element releases X-rays with a specific signature. Your email address is used only to let the recipient know who sent the email. How was it discovered? To do this, we used a type of particle accelerator called a synchrotron radiation lightsource located at Stanford University in California. It lived about 300 million years ago. It resembled a foot-long squid with eyes on stalks and a long, skinny trunk that ends with a claw. This may help to further narrow down the group of animals to which Tully belongs. [4] Sallen, et al.

Further criticism was drawn towards the identification of the blocks of the body variously as gill pouches and muscle blocks (myomeres), despite the lack of differentiation in the structure of these blocks. Where do we go from here? [4], In 2020, McCoy and colleagues used Raman spectroscopy to identify the molecular bonds present in the organic material preserved with Tullimonstrum. The Tully Monster, or Tullimonstrum gregarium, has long been one of the most popular Mazon Creek fossil specimens. When the creatures died, they were rapidly buried in silty outwash. This is a holotype fossil specimen of the Tully monster. Fossil of Tullimonstrum- Took the picture at Museo di Storia Naturale di Milano – Credit : Ghedoghedo. Based on samples from multiple points in the body, they identified the organic material as representing proteins and their decay products (as is seen in vertebrates) as opposed to the polysaccharide-based chitin (as is seen in arthropods), supporting the interpretation that Tullimonstrum is a vertebrate. The Tully Monster, or Tullimonstrum gregarium, has long been one of the most popular Mazon Creek fossil specimens. Even if the eye of Tullimonstrum is homologous with vertebrates, it could be a tunicate (the larvae of which have pigmented eyes and tail fins), a lancelet or an acorn worm (both of which have gill openings and a notochord), or a vetulicolian. He was searching for fossils inside of 300 million year old ironstone nodules found in the Francis Creek Shale. This suggests the animal may not have been a vertebrate, contradicting previous efforts to classify it.

These include a linear feature in the fossil interpreted as evidence of a gut, the light and dark banding of the fossil and the peculiar grasping claws of its mouth. This would necessitate the convergent re-evolution of grasping jaws. Interesting things. Its species name, gregarium, means common. [2], Tullimonstrum had a pair of vertical, ventral fins (though the fidelity of preservation of fossils of its soft body makes this difficult to determine) situated at the tail end of its body, and typically featured a long proboscis with up to eight small sharp teeth on each "jaw", with which it may have actively probed for small creatures and edible detritus in the muddy bottom.
