Species

These four species belong to the genus Mesoderus:

  • † Mesoderus magnus Prokin & Ren, 2010
  • † Mesoderus ovatus Prokin, Petrov, B. Wang & Ponomarenko, 2013
  • † Mesoderus punctatus Prokin, Petrov, B. Wang & Ponomarenko, 2013
  • † Mesoderus ventralis Prokin & Ren, 2010
gollark: There actually are worries about development of this stuff slowing down.
gollark: <@!336962240848855040> As far as I know 3nm does not actually exist yet, and there are a bunch of possible sizes you could use.
gollark: > The 22 nm node may be the first time where the gate length is not necessarily smaller than the technology node designation. For example, a 25 nm gate length would be typical for the 22 nm node.
gollark: As far as I know it *used* to actually be a measure of something, but they hit issues around... 22nm or something, don't really know... and despite said measure not changing very much the processes kept getting better, so they just reduced them.
gollark: I mean, generally if the number goes down the density of the transistors goes up, but it's not an actual measurement of anything.
