Monotremes: Egg Laying Mammals of Action

Please enjoy this video examining the evolutionary history of the unique Australian Monotremes, a group the includes the modern platypus and echidnas in addition to a select number of extinct toothy forms from the Cretaceous and Cenozoic.

Somehow the term ‘puggle’ fits perfectly with how adorable and chubby the baby echidnas are

[RafaCB]

Equidinas always make me think about how many extinct mammals could have "spikes", and if it would be able to be known in the fossilization process

He's a semi aquatic
Egg laying mammal of action
(Doo-bee-doo-bee-do-bah)
(Doo-bee-doo-bee-do-bah)
He's a furry little flatfoot
Who never flinched
From a fra-ee-ay-ee-ay (Fray)
He's got more than just mad skill
He's got a beaver tail and bill
And the women swoon
Whenever they hear him say
(Perry's sound)
He's Perry, Perry the platypus
(You can call him Agent P)
Perry
(I said you can call him Agent P)
Agent P
Agent P
Agent P

Its a good day when Dr. polaris uploads

Puggles is such an adorable name for a baby

[TrajGreekFire]

fun fact - platypuses in Tasmania are bigger than mainland ones

[t-r-e-x]

Doof: A patagorhynchus?
*It puts on a hat*
Doof: *Perry the Patagorhynchus!*

[gheathen]

"A monotreme?" puts on hat, "Perry, the monotreme?!!"

[bennyworm]

I enjoy the Perry the platypus reference in the title

I loved Egg Laying Mammals of Action's first record.

Another Echidna oddity, they can dig straight down. They will only ball up if they cant dig. If caught out in the open on soil their go to is to submerge leaving only their spines showing. Also, if balled up they can flex their spins such that they work against each other and jab you.

Good news, they are doing rather well, with them being much more common now than they were 50 years ago (at least in western NSW). My recently passed father opined that this could be a result of there being more fertilizer being used resulting in more biomass in the environment generally including food for the Echidnas.

The destructive pests foxes and cats, that have been so disastrous for many native mammals, don't phase Echidnas one bit.

Living in Australia, I can say that monotremes are quite rare and shy. I have encountered wild echidnas only a handful of times over the last decade. But I have never encountered a wild platypus. Thy are extremely shy.

[zray]

We need an entire video on how on earth you can know something was a monotreme from one single molar.

[robinmatz]

Great content, instant like at the mention of Perry

[parmaxolotl]

Knuckles behaves more like an echidna than he looks. He tends to dig quite a bit and also is capable of sensing hidden objects without physically seeing them.

[gattycroc]

I first learned about Monotrematum when I was looking up creatures of early Cenozoic South America and I was surprised that the continent had its own native Monotreme. this along with the newly described Perucetus Colossus in Peru is just screaming for more paleo media about South America during the Paleocene to Miocene since all we got is Titanoboa Monster Snake and the Kelenken segment of Prehistoric Predators.

Awww, indeed! That puggle was looking right at me! Adorable!
that you used the proper plural, "platypodes", Dr. P!

[AntoekneeDE]

I really enjoyed this, and completely value the appraisal. The Platypus may look at us and laugh at our primitive faces devoid of electro sensory gubbins, and they have of course constantly adapted to their environments for just as long as any other mammal alive today. I feel we’re lucky to be around to see them, however, as evolution over periods of extinctions doesn’t seem to favour highly derived animals, and with only two main groups around, the odds that we have been able to explore oviparous mammals and some other cynodont traits that the other descendants have lost such as their skeletal anatomy of the neck and shoulder, and sclerotic rings, are incredibly small. Monotremes probably not only tell us about our common ancestry with each group preserving traits the other has lost, to build a more complete picture, but they also tell us a lot about non-therian mammals where viviparous reproduction was more likely the exception than the rule of this is truly a diagnostic of therian lineage

[erichtomanek]

Excellent video, informative and visually appealing.
I wish fossils of a platypus species are found that somehow show they built dams, like a beaver.
Also, fossils of a truly large platypus that due to evidence of one thing or another, gets the common name Crocs' Bane.
