description

Pētījuma mērķis ir noskaidrot Franas stāva psammosteīdu ārējā skeleta mikromorfoloģijas likumsakarības un to izmantošanas iespējas taksonu diagnosticēšanā, pētīt dermālo pauguriņu mikroskulptūru, izmantojot skenējošo elektronmikroskopu. Pētījuma rezultāti varētu tikt izmantoti biostratigrāfijā. Apskatīta Psammolepis undulata, Psammosteus maeandrinus un Ps. megalopteryx dermālo pauguriņu morfoloģijas mainība atsevišķu branhiālo plātņu ietvaros, sastādītas plātņu zonālās uzbūves shēmas. Dermālo pauguriņu forma varētu būt saistīta ar plātnes un dentīna pauguriņa augšanas tempu attiecībām. Dermālo pauguriņu virsmā ir atrastas mikroapertūras, mikropauguriņi, poligonālie veidojumi. Mikropauguriņi norāda uz dermālā pauguriņa augšanas īpatnībām. Poligonālie veidojumi atspoguļo dermālo pauguriņu ietverošo mīksto audu stiprināšanas mehānismu.
