Název v původním jazyce

A Silurian oncocerid with preserved colour pattern and muscle scars (Nautiloidea)

Popis výsledku v původním jazyce

New genus Euryrizocerina is striking for two features ? the preservation of shell colouration and muscle attachment scars. These features are reliable for taxonomy and palaeoecology of nautiloids. The colour pattern consists of irregular pulsed transverse bands that differ from the colour patterns known in other oncocerids. Oncocerids exhibit multiple paired muscle scars and there is uncertainty whether these represent an original metamery or a derived feature. Euryrizocerina possesses four pairs of retractor muscle scars, but its ancestor possess multiple pairs of muscle scars around body-chamber. The high evolutionary plasticity of muscle attachments patterns suggests that the muscle complex and its attachment to the shell was under adaptive controland is more likely to reflect the form of the shell and the mode of life of the organism.
