|Anterior half of Skeemella. |

Skeemella had a long, skinny tail with two flukes that formed a paddle at the end of the tail. This picture shows Skeemella, the large elongate animal, and a group of the trilobite Peronopsis. The Peronopsis are probably searching for carcasses of Elrathia kingii, because they were some of the most common food sources that a scavenger like Peronopsis would be able to eat.
I believe that Skeemella may have been nocturnal, because its long tail would drag behind and in the day could be seen and grabbed by a predator. But in the nighttime, the big predators were either sluggish, inactive, or could not see well in the darkness, so Skeemella could be safe. But that's just my hypothesis.
|My interpretation of Skeemella with a group of Paronopsis.|
Skeemella had a tough carapace shaped like a fingernail, a beak-shaped mouth, no eyes, and two lobe-like extensions on the glob-like anterior part of the body.
