Show us yours: convergent evolution

Convergent evolution is all about two distantly related organisms evolving similar appearances in order to adapt to the enverionment they live in. The wing is a perfect example of convergent evolution!

sea turtles and Henodus

Never heard of a Henodus before Mihnea!

I have learnt something new today - thank you.

Phytosaurs lived during the Triassic period when most crocodile relatives were terrestrial. They're easily distinguished from true crocodiles by the position of their nostrils, which is much closer to the eyes. There are many other dissimilar features, but that's the easiest external marker. Despite the resemblance, phytosaurs aren't closely related to crocodiles, instead being stem-archosaurs, and hence about equally related to both birds/dinosaurs and crocodiles.

A interesting SUY

Indeed !

Thanks for bringing this up again, Hali

That's a beautiful example of convergent evolution. I think that I belong there once I am a sarcosuchus. Such incredible figure that redondasaurus.

comparison between Panthera tigris (from Papo), a true cat and Thylacoleo carnifex (from Southlands), a cat-like marsupial.

2 noteworthy differences (moreover the marsupium of course!): the kangoroo-like tail and incisifs-fangs of Thylacoleo..

The cat form appeared several times in the past, among carnivora genus with nimravids, among placental mammals with creondont oxyaenidae, among marsupial mammals with Thylacoleo and Thylacosmilus..

.."Hi mister Carnifex!.. how do you do?..
- ow! mister Tigris!.. well, as well as a disapeared species!.."  :)

Funny presentation! These two are convergent in every single aspect, including the design concept. Two wonderful figures also with a high quality. Thanks Caracal!

Wonderful idea

on left, true felids Machairodus, on right, felid-like Nimravid Eusmilus.
The "saber-tooth tiger" form appeared twice amongst Carnivora genus: first time with Nimravidae and later with Felidae. Nimravids had generaly shorter legs than Felid's ones and presented, at the lower jaw, apophysis which protected  upper fangs when the mouth was closed like later, somes felids machairontids (Meganthereon and Homotherium).

According to some  Paleontologist, the Felidae are closer to Hyaenidae or Viverradae than to Nimravidae.

these 2 Bullyland replicas are very interesting because they represent 2 very few edited species. I don't know other Machairodus from others main brands (the Starlux one is not actually a Machairodus species) and I have also this Hinstar other Eusmilus (but I know another one from Geoworld):

..like the others Hinstar prehistoric mammals, the sculpture which has been wanted spectacular, is not very accurate and its jaw apophysis are far too exagerated!..

you guys should dig these examples of convergent evolution:

marsupial mole (Mammalia: Notoryctemorphia: Notoryctidae)
true mole (Mammalia: Eulipotyphla: Talpidae)
mole cricket (Insecta: Orthoptera: Gryllotalpidae)

I love this topic

another mistake must be corrected on "Toy Animal Wiki", the Instar Eusmilus above, is named and placed with True saber tooth Homotherium. But "Eusmilus" is writed under its belly , hence it should be placed with "false saber tooth Eusmilus"
Sorry to be "fussy" about cats!..

Are you sure the figure with jaw apophysis is not a THYLACOSMILUS?

Thanks for your observation. I renamed and replaced it.

Well, Valérie made me doubt and I check, "Eusmilus" is NOT writed under its belly!.. I apolologize for that mistake ..and don't understand why I was so sure of that.. probably by confusion with Bullyland Eusmilus!.. I think it has been sold to me on this name and it's on this name that it's presented on "Toy Animal Wiki" by "brands" at "Hinstar Toy".. Anyway it can not be an Homotherium because of its long tail and short legs but a Thylacosmilus?.. why not,.. it would explain its so long jaw apophysis (even if the tail is not a Thylaco's one but with a so few accurate replica..)

I've found it strange that being the TAW picture from Beatrice, that she hadn't noticed it was marked. She always examine her figures in detail. She even mentions it [You must be registered and logged in to see this link.] However, it was not the first time a figure was found with different markings. So which species should I use? Which do you think is closest to the figure? I admire you in this once these figures look somewhat cartoonish and not easy at all to identify. Meanwhile, I will ask Beatrice if she listed it over a guess or if she found any official info.

Yes Rogério, it's not easy to identify so unaccurate replicas but I am (almost!) sure it's an Eusmilus because of its long and supple tail which doesn't look at all the Thylacosmilus one.. I examinated on web some thylacosmilus figurines, they all present a kangoroo-like tail, even the cartoonist Geoworld one!..  all these brands often produce the same known taxons maybe under the influence of some books pictures like this one:

This draw, from Sergio illustrator, shows an Eusmilus attacking an other nimravid: the Nimravus (which could escape and survive in spite of its terrible wound!). We can observe its long feline tail and its deep jaw apophysis, this draw could have been the model for this rather bad Hinstar replica!..

I asked Beatrice and she haven't got the information from any official source. Those are just guesses or identifications found around and waiting for better guesses. It is just what you did so it is a eusmilus now.

..I think it's right!.. thank you Rogério! :)
