Eisenackisyrinx curvatus is an organic microfossil known only from the Ordovician erratic boulders of Baltic origin. Its systematic position is unclear.

    
Mierzejewski (1986, p. 198) described it as follows:

"Strongly bent irregular tubes of black, glittering opaque periderm. Tubes about 100-210 micrometers in diameter, narrowing to 30-50 micrometers at both ends, with maximum length over 2 mm."

Type horizon: Llanvirn (
Eoplacognathus pseudoplanus Zone).
