The carbonate combined with iron from the groundwater around the remains, forming encrusting nodules of siderite. Although arthropods do not have the melanosomes of vertebrates, some do have convergently evolved spheroid eye cells that may be preserved similarly; however, these pigments (ommochromes and pterines) have unique chemical signatures which were not found in the eyes of Tullimonstrum. 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.

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. To our surprise, we then found the same pattern could be seen in fossilised vertebrates and invertebrates found at Mazon Creek. [13], A 2017 study rejected the above conclusions. [4][1] Since it appeared to lack characteristics of the well-known modern phyla, it was speculated that it was representative of a stem group to one of the many phyla of worms that are poorly represented today.

But the copper also wasn't identical to that in the invertebrates we studied. and Terms of Use. Your email address is used only to let the recipient know who sent the email. A broader analysis of the chemistry of melanosomes and other pigments in the eyes of a wider range of invertebrates would be a good next step.

The Tully Monster, or Tullimonstrum gregarium, has long been one of the most popular Mazon Creek fossil specimens.
