The cephalaspids of Great Britain, By Erik Andersson Stensi\uf6 and British Museum (Natural History) Cite. Topics: Cephalaspidea, Great Britain, Palaeontology, Palaeozoic Cited by: Cephalaspis (meaning 'head shield') is a genus of armoured fish in the early Devonian about million years ago (mya). It was one of the jawless fishes, or ostracoderms, which were common at the time.. They were discovered in the first half of the 19th century in the Old Red Sandstone of Britain. Louis Agassiz named it in He had been to Scotland, and seen Hugh Miller's : Osteostraci. Cephalaspis, one of an early group of vertebrates called ostracoderms, possessed an external bony head shield, but probably its internal skeleton was not ossified to any great extent. Its eyes were situated on the dorsal side of the flat head; the ventral placement of its mouth indicates that Cephalaspis was a bottom-feeding is probable that Cephalaspis lived by straining organic.

Description. Like its relatives, Cephalaspis was heavily armored, presumedly to defend against predatory placoderms and eurypterids, as well as to serve as a source of calcium for metabolic functions in calcium-poor freshwater had sensory patches along the rim and center of its head shield, which were used to sense for worms and other burrowing organisms in the mud.   Like with all DK books, this book is absolutely beautiful.

The book IS expensive, but well worth the cost, and I have used it innumerable times to research a figure, read the text, or to just enjoy the s: 5.
