Lagerpetidae: The Tree Climbing "Rabbit Reptiles" of the Triassic Period

[@chimerasuchus]

There have been several notable discoveries relating to Lagerpetidae and Pterosauromorpha since this video came out. Two more pterosauromorphs, Faxinalipterus and Maehary, have been found. Faxinalipterus is a lagerpetid while Maehary is a more basal pterosauromorph. Second, a recent paper found that Scleromochlus was likely not only a pterosauromorph after all, but also a lagerpetid. This brings the total size of the to eight species and six genera.

Thats interesting. However the new question is weather or not Pterosaurs evolved from lagerpids or splitted of from them.

[@tristanbourgeois7658]

According to a new study by Rodrigo temp muller, the maehary bonapartei is classified as a more derived species of gracilisuchidae that emerge later during the triassic than the others, during the early norian stratigraphy of the late triassic. Several other species like turfanosuchus live in the anisian stage, yonghesuchus during the ladinian, parvosuchus aurelioi (late ladinian to early carnian), gracilisuchus stipanicicorum during the early carnian. The maehary bonapartei taxon is a part of pseudosuchian rather than being classified as a close relative of pterosaurs and being a basal pterosauromorpha according to recent studies. The gracilisuchidae clade is a early diverging clade of suchians, that exist even before the first aetosauriformes, aetosauria, erpetosuchia, ornithosuchia... The paracrocodylomoprha especially the shuvosauridae exist since more than 248 millions years ago during the middle triassic, anisian stage, The earliest paracrocodylomorpha dated to the olenekien (last stage of the early triassic). And preceed the first avemetatarsalia to ever exist (possibly).

Such cute little archosaurs. Thanks for such an insightful video on such an strange family of animals! Its not hard to imagine that something very similar might have been the ancestor of ptersaurs.

I'm safe to say that this is the best video you've done so far, with every video I'm seeing a constant improvement, plus I really enjoy videos like these focused on a group of animals

[@dinohall2595]

This may be the best video on the channel, and that's against some stiff competition. So much information packed into these eleven minutes that there's not a single stale moment. I always thought the lagerpetids were dinosauromorphs (I wonder if the similarities to pterosaurs in the semicircular canals could be convergent because they both had agile lifestyles?), but seeing the evidence that they're actually a transitional form leading to pterosaurs just makes them even more awesome!

[@jordansefton]

Thank you for constantly producing such good videos and working so hard! Constantly producing videos that I don’t think anyone has done before and doing them perfectly!! Had to turn notifications on because I can’t miss your uploads!!❤️

[@posticusmaximus1739]

Great video. Would be interesting to see coverage on protorosauria like ozimek, sharovipteryx, and possibly tanystropheus. These were the almost pterosaurs as they were evolving in the direction towards flight but never fully took off and were superceded.

[@generaldissatisfaction5397]

How cute would a leaping kangaroo reptile be?? I wonder if this sort of lifestyle is what lead to pterosaurs gaining flight, a "ground up" stage of proto-flight. Great video.

Things I wish I could have as pets.

[@golddragonette7795]

Scleromochlus has a special place in my heart, these lil rabbit reptiles will be joining it!

[@maozilla9149]

good show

[@vassa1972]

Good stuff Happy holidays to all

[@MaryAnnNytowl]

Happily given like, and humorous or insightful comment, for the Almighty Algorithm, here. 👋😊 Watching many of these in a row, and doing other things, so you get a copypasta. Carry on.

[@stefanostokatlidis4861]

Large insectivorous animals catch small vertebrates from time to time, so it is not unlikely that those animals did it too. Also, it seems that today this type of lifestyle does no longer exist. Arboreal agile hunters are either flighted ones like birds or climbers like lizards and nothing in between.

[@cerberaodollam]

I want them as pets, like, now. (Hopefully my modern felids don't eat them though)

[@shockdrake]

What is the genetically closest modern animal of Pterosaur?

[@chimerasuchus]

@@shockdrake Funnily enough, birds.

[@cerberus6654]

I finally figured out who you are! You are Jay Baruchel aren't you?

[@chimerasuchus]

No.

[@johnathanblackwell9960]

I don't know why, but they sound adorable
