Eospondylus primigenius – The rare treasure from Bundenbach<\/span><\/h2>\n

A filigree jewel for connoisseurs of Devonian brittle stars.<\/span><\/h3>\n

While species such as Furcaster are the classics of the Hunsr\u00fcck slate, Eospondylus primigenius<\/strong> is a real specialty. It is closely related to the genus Furcaster<\/em> – which can be recognized by the characteristic ambulacral plates fused into vertebrae – but it is much rarer in terms of find frequency. In excellent condition, this genus is therefore often the target of passionate specialists. <\/span><\/p>\n

 <\/p>\n

The fine details – anatomy in a class of its own:<\/span><\/h3>\n
    \n
  • Characteristic body disk:<\/strong> The most striking difference to its relatives is the round disk. This only includes two arm vertebrae and is covered with tiny platelets arranged like roof tiles – a structure that gives the fossil an almost scaly, very elegant texture. <\/span><\/li>\n
  • Boots and sickles:<\/strong> The true mastery of nature is revealed under the microscope: The vertebral halves of the arms are distinctively boot-shaped, while the side shields have an elegant sickle shape.<\/span><\/li>\n
  • The showpiece: The spines:<\/strong> The absolute highlight, however, is its spines. Excellently preserved and masterfully prepared, the exceptionally long spines give the animal an almost radiant aura on the dark slate. <\/span><\/li>\n
  • Classical features:<\/strong> As with all true Ophiuroidea (brittle stars), the madropore plate is on the underside (oral) – an important detail for scientific classification.<\/span><\/li>\n<\/ul>\n

    Why an Eospondylus belongs in every Hunsr\u00fcck collection:<\/span><\/h3>\n

    Due to its moderately long arms, this brittle star appears very compact and harmonious. It is not as expansive as a Furcaster decheni<\/em>, but impresses with its significantly higher rarity and the unique platelet structure of its disk. <\/span><\/p>\n

    Quality and preparation<\/span><\/h3>\n

    As the long spines and delicate disk plates are extremely fragile, this genus requires the utmost precision when uncovering. A piece in which the “sickle shields” and the full crown of spines are visible represents a significant enrichment for any documentation of the Rhenish Lower Devonian. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
