  • Fish
  • Paleontology
CONT

The name Arthrodira means "jointed neck" These advanced preditory placoderms had a movable joint between the head(cephalic) and the thoracic(body) armor... The mouth is interesting because as the lower jaw moved down the head shield moved up, thus giving a wide gape. Like all placoderms, they lacked teeth, instead using the sharpened edges of a bony plate as a biting surface.

Domaine(s)
  • Poissons
  • Paléontologie
OBS

Les Arthrodires forment un vaste groupe multiforme de «Poissons». [...] il est clair qu'ils sont de vrais Gnathostomes, qu'ils appartiennent aux «Elasmobranchiomorphi» [...] et qu'ils sont surtout apparentés aux Holocéphales.

OBS

Exemple : «coccosteus» [...] du Dévonien moyen. Il a des «appendices pectoraux, mobiles, d'une seule pièce» [...] et une denture de «carnivore».

  • Mining Equipment and Tools
CONT

The principle of movable shield support is well known : once the working place has been fixed within the bounds of a pillar the production face is pushed forward together with the installed support without any further expenditure of time and money for setting up a new one; the weight of the support and the rock pressure are used for shifting the support.
