Have you heard ever about the mysterious Tully monster? For the first time speak about it in the 1950-ies, when the collector of the fossils named Francis Tully found the first remains in the petrified strata of the river Mazon Creek in the Central part of Illinois (USA). It is believed that the Tully Monster or Tullimonstrum, was a sea creature that lived in the muddy coastal waters of Mazon Creek. However, according to the latest study, which was published in the journal Proceedings of the Royal Society Proceedings B, the mysterious 300-year-old “monster Tully” is probably quite different from what in the past believed it to scientists as the results show, Tully monster was not spinal.
Mysterious Tully monster
Tullimonstrum, also known as monster Tully, lived 300 million years ago. however, the fossils were first discovered 60 years ago. In 2016, a study was conducted, the results of which Tully is described as a vertebrate animal. According to researchers, the tally was a strong cartilaginous rod, which supported the body and gills. Thus, it was assumed that Tully was predatory vertebrates, like some primitive fish. But what else is known about this mysterious monster?

Researchers believe that the tally could grow to three meters in length, while his body was thin and segmented. Eye of the sea monsters were planted at each end of a long hard rod on the top of the head, and he was the tail fin. However, the weird part is that the jaw Tully monster was at the end of a long proboscis, which suggested that he eat food hidden deep in the mud or in rocky crevices. However, despite its intricate appearance, researchers believe that the mysterious monster was not spinal. Moreover, in the petrified eyes of creatures discovered unusual entries.
The eyes of the Tully monster was allowed to reveal his secret
In the course of the study, the researchers used a particle accelerator to determine the ratio of elements in the eyes of modern vertebrates and invertebrates. Thus, the experts were able to make a comparison with the ancient monster Tully. They found that the ratio of zinc to copper in the melanosomes of the eye was more similar to that of modern invertebrates than in vertebrates.
Melanosoma is the organelle contained in cells of the animal Kingdom, consisting of melanin and other light-absorbing pigments.
By bombarding samples with outbreaks of radiation scientists were able to “excite” elements inside — in this state, each element produces a signature that allows them to determine what elements make up the eye. Dr. Chris Rogers, a researcher in the field of paleobiology from University College Cork, the study’s lead author, believes that the chemistry of the eyes of Tully and the ratio of zinc to copper was more like one used for invertebrates than vertebrates.

Scientists say that this suggests that the animal may not have had the spinal. This is contrary to previous attempts to classify it. The research team also found that the eyes of the fossils contained copper of a different type than the modern invertebrates, which they studied. For this reason, researchers are unable to classify Tully as one of them.
