Talk:Meganeura

message: The page says: The word Meganeura means “Big Genes”.  This is almost certainly incorrect, particularly in view of the naming date; in 1885 nobody has heard of genes yet.  AFAIU, meganeura means “big nerves”, but it probably refers not to actual nerves but to the network of air-filled veins in the wings (cmp. insect wing and Neuroptera).  My best guess would be “large-veined”, and I changed the page accordingly. Freederick 10:31, 11 January 2007 (UTC)

message: At the risk of making the pop culture section larger than the scientific section, should it be mentioned that Davis Schwimmer's character on Friends (a paleontologist) had a reconstruction of a Meganeura as wall art in his apartment? 172.130.4.65 13:58, 6 July 2007 (UTC)

Logically, if modern insects can breathe this way, as appears to be the case from the 'more recent research', which could hardly have been done on fossil insects, then something other than respiration/oxygen availability keeps modern insects from reaching the impressive sizes of Meganeura et al; possibly this may be compeition with birds.

thread_title: Respiration

message: I could not find a reference to the scientific literature supporting the statement that Meganeura preyed on amphibians. I also can't imagine how anyone would be able to infer that from the fossil record. Living dragonflies capture their prey in flight. This looks like a made-up factoid, so I removed it.  — Preceding unsigned comment added by 71.59.208.88 (talk) 22:47, 30 July 2013 (UTC)
thread_title: Amphibians as prey

message: The last sentence seems a bit "out of the blue" to me. Could someone with knowledge on the subject elaborate this sentence a bit? Because it's quite conflicting with the other mentioned theories. Maybe adding another paragraph, or have the known theories in a list as a preamble with elaboration under it? 217.121.65.15 (talk) 20:48, 6 December 2016 (UTC)

message: I'm unable to find if m.brongniarti is a valid species. The website, Fossilworks, states m.brogniarti is a synonym to m.monyi.

thread_title:  Species? 

message: The following § might infer, without implying (rather only on the issue of respiratory "flight energetics" limiting size growth bounds on the species due to oxygen intake) that the mechanics of birds and these insects follow similar rules – yet birds have unidirection breathing and not, as it seems to say with the ref., 'rapid cycles of tracheal compression and expansion'. Does this implication of two part drawing/releasing of breath hold for agonflies? ….if soshort caveat on the di added, despite the issue at hand indicating the shared evolutional stressors on the condition of their shared 'flightedness' being effected by their respiration.
It seems if such a disparity in breathing type exists it should be logically distinguished here, in as minimal a way possible, or the allusion has a glaring point of misleading contention to the fact of the matter - at least when using the other as a matching category which it would otherwise entail, seemingly wholesale, some mutual situation which both arise from.
“If this hypothesis is correct, these insects would have been susceptible to falling oxygen levels and certainly could not survive in our modeo breathe, with "rapid cycles of tracheal compression and expansion".[6] Recent analysis of the flight energetics of modern insects and birds suggests that both the oxygen levels and air density provide an upper bound on size.”--[[Ustember 2021 (UTC)
:Do you have a reliable source that supports the position you are outlining here?  If so can you supply i to be honest, so I am guessing at what you are attempting to convey.--Kevmin § 01:09, 28 September 2021 (UTC)
