Dear Franz-Josef,
"Tremalkanal" is (to explain for those unfamiliar with German)
"Tremal" "channel", e.g. a "channel" with a "trema".
A "trema" is today in dentistry (tooth medicine) a true diastema.
Related ("somehow") a "small gateway between the cutting-teeth",
e.g. the two central teeth in the mouth.
Being _unfamiliar_ with above fossil group I would think wether a
"small gateway between tooth-like" (morphological of course) features
could be meant.
Consulting a wordbook of dentistry (in the sense of a tooth-clinic)
might help. Possibly they have equivalents to the "Visser".
