They opened between the diamond-shaped platelets which separate the dorsal from the ventral protect. Sacabambaspis is an extinct genus of jawless fish that lived in the Ordovician interval. Sacabambaspis lived in shallow waters on the continental margins of Gondwana.[1] It is one of the best recognized arandaspid with many specimens.
Present Clear Proof Of A Sensory Structure Generally Known As A Lateral Line System The
The tubercles of Arandaspis are drop-shaped and scalloped, these of Sacabambaspis and Andinaspis oakleaf-shaped, and people of Porophoraspis are perforated by large pores. Which of these sorts of ornamentation is primitive for the group is unknown, though one might observe that the earliest identified arandaspid fragments are of the Porophoraspis type. I was scrolling by way of my feed and I discovered an extinct fish called Sacabambaspis, and I thought I should share some information I learned about it.

Also it had slender branchial plates which hyperlink these two alongside the edges, and canopy the gill area. The eyes were far ahead and between them are possibly two small nostrils they usually, which are surrounded by what's considered endoskeletal bone, and putative nostrils, are found at the extreme anterior of the top, one of many diagnostic features of the arandaspids. The rest of the body was covered by lengthy, strap-like scales behind the top protect. Sacabambaspis had a large amount of armor on its head, which nearly acted like a defend, it was created from a large higher plate that rose to a deep curved lower plate. This defend was ornamented with attribute oak-leaf formed or tear-drop formed tubercles.
