Labellums
Labellums are a type of decorative appendage found on certain species of marine invertebrates, primarily known from fossil evidence. These structures are typically flattened and often leaf-like or fan-shaped. Their precise function remains a subject of scientific inquiry, with several hypotheses proposed.
One prevailing theory suggests that labellums served a sensory purpose, aiding in the detection of food particles
Some paleontologists propose that labellums might have had a role in locomotion, although this is less widely
The morphology of labellums varies considerably among different fossil specimens, indicating adaptation to diverse ecological niches.
