Its genus name refers to the fact that the shield is composed of hundreds of tiny scales. Although it is regarded as a heterostracan, its exact placement is regarded as incertae sedis , as the fact that it is currently impossible to discern where its dorsal and ventral plates which are made up of a mosaic of the aforementioned tiny scales end or begin. Some experts regard it as being descended from the basal heterostracans of the Silurian .

It is related to other Ordovician fishes, such as the South America n Sacabambaspis , and the Australia n Arandaspis . Basic Anatomy Astraspids are hypothesized to have been about 200mm in length. They are supposed to have had a mobile tail covered with small protective plates 1mm and a head region covered with much larger plates 2mm . The specimen from North America described by Sansom et al., 1997 is to have had relatively large, lateral eyes and a series of eight gill openings on each side. The specimen was generally oval in cross section. The protective bone bony plates covering the animal were composed of aspidin chemically similar to shark modern shark s teeth , covered by tubercles composed of dentine . It is from these tubercles which are generally star shaped that the name Astraspis literally star shield is derived. In popular culture It has a small cameo in the 2003 BBC series Sea Monsters A Walking with Dinosaurs Trilogy , a spin off to the famed Walking with Dinosaurs , where Nigel Marven uses a dead Astraspis as bait to attract a sea scorpion . The creature is identified in the series novelisation. It is also said to be an armour plated fish in the documentary, whereas is more closely related to the modern lamprey . Astraspis was also featured in Animal Armageddon .

It is related to Astraspis . Description Image Sacabambaspis.JPG thumb left Fossil Sacabambaspis had a head shield made from a large upper dorsal plate that rose to a slight ridge in the midline, and a deep curved lower ventral plate. Also it had narrow gill branchial plates which link these two along the sides, and cover the gill area. The rest of body was covered by long, strap like Scale 28zoology 29 scales behind the head shield. The eyes were far forward and between them are possibly two small nostrils , and the mouth was armed with very thin plates Mouth oral plates . The fossils of Sacabambaspis and Astraspis show clear evidence of a sensory structure lateral line system . The arrangement of these organs in regular lines allows the fish to detect the direction and distance from which a disturbance in the water is coming. References Michael J.
