Peace and grace.
Nofri ya sayed Samer,
The Liturgy of St. Mark is still in use, but is known as the Liturgy of St. Cyril. St. Cyril's is
wholly the Liturgy of St. Mark, translated into Coptic, and with some additional prayers. St. Cyril's is traditionally prayed during Lent and also on the feasts of St. Mark the Evangelist and Martyr, and St. Cyril the Pillar of the Faith. Some traditions say that it should be prayed for all of Kiahk as well (traditionally the month in which we venerate St. Mary during the fast of Advent), since it was St. Cyril who most ardently defended the Theotokos.
That Liturgy is unique from the rest, it is very penitent, but it has also a different structure. The Anaphora comes after all the Litanies! This was done so that the catechumens could get the most they possible could out of the Liturgy before they were kicked out!

I've never heard of the Liturgy of St. Dionysius being extant, let alone used - though I heard of the Liturgy of St. John the Beloved being used in our churches a couple of time. That Liturgy used to be in the Coptic rite, but died out and was continued in the Ethiopian Orthodox church.
Pray for me!
