Question for Madagascar ...

I am looking up Madagascar on the google site Palaeocritti.

Brief review of what periods mean. Upper is more recent than lower of each. And middle comes in between.

The named labels are from less to more recent : Permian, Triassic, Jurassic, Cretaceous.

This means that a creature from "Upper Jurassic" should be older than any creature from Cretaceous, upper or lower, and more recent than any from Lower Jurassic, any Triassic or any Permian.

Now, I am looking - or was a moment ago and will again - at a specific creature from Upper Jurassic.


As it is an ichthyosaur, it lived in water.

This any creationist as much as any evolutionist will admit.

Brachypterygius extremus (which is one of them) has an age and distribution of :

Kimmeridge Clay (Kimmeridgian, Upper Jurassic)

Smallmouth Sands, Dorset, UK; Wiltshire and Cambridgeshire, UK; Volga and Saratov regions, Russia; Madagascar.

And sure enough, the page for Madagascar is - no, wait, it is simply listing genus. I'll look at the page to see if some other species is also from Madagascar.

Brachypterygius mordax - no.

Brachypterygius cantabrigiensis - no.

So, it is actually just Brachypterygius extremus which is from Madagascar too.

This means, some place on Madagascar is labelled as Kimmeridgian, Upper Jurassic and you found Brachypterygius extremus there.

All the other creatures listed for Madagascar are - it would seem - land animals.

Rahonavis ostromi
- Horizon:
Upper Cretaceous (?Campanian) Maevarano Formation

Type Locality:
Mahajanga Basin, northwestern Madagascar

Question part 1 : was the Brachopterygius found below any Rahonavis ostromi or was the Rahonavis ostromi found above any Brachopterygius?

Any Cretaceous is supposed to be more recent than Upper Jurassic.

Majungasaurus crenatissimus:

Anembalemba Member, the uppermost white sandstone stratum of the Maevarano Formation, Upper Cretaceous (Maastrichtian)

Mahajanga, Madagascar

OK, found along the Rahonavis. Not sure how close or how far.

Question part 2 : was the Brachopterygius found under any Majungasaurus? Or was the Majungasaurus found above any Brachopterygius?

Question part 3 : if you plot the space between Rahonavis and Majungasaurus on a map, or between more than one of each (Majungasaurus has more than one cranium, so more than one specimen) (Rahonavis was just one skeleton), was there any Brachopterygius found in between these, either physically lower in the ground, or in such a place as to indicate present surface was physically lower?

The questions 2 and 3 multiply if you add the several specimens of Masiakasaurus knopfleri (UA 8680, FMNH PR 2108–2182, UA 8681–8696) (Locality: Mahajanga Basin, near the village of Berivotra, northwestern Madagascar), and of the somewhat fewer Behemoths of Rapetosaurus krausei label. (We deal with : UA 8698 as holotype and then the referred specimina FMNH PR 2184-2192, 2194, 2196, 2197, 2209, 2210, UCB 92829). (Mahajanga basin, northwestern Madagascar.)

They multiply just a bit more, if you add Simosuchus clarki (Crocodylomorpha Notosuchia Chimaerasuchidae) and Araripesuchus tsangatsangana (Crocodylomorpha Notosuchia), who, poor crocs, have no separate pages (let's suppose they could shed crocodile tears for that!).

But all so far, except the Brachypterygius, are from Maevarano Formation, Mahajanga, Madagascar, Upper Cretaceous (Maastrichtian).

We also have four types of Eosuchia - sounds like crocs, early or dawning crocs - from Madagascar, Upper Permian (Wuchiapingian), outside and inside Lower Sakamena Formation. As well as from Middle Sakamena Formation, Madagascar, Lower Triassic (Induan). At least three places or "layers" with crocs.

Now, recall, these are supposed to be earlier than Upper Jurassic.

Question part 4 : is Brachopterygius found above any of these or is any of these found below a Brachopterygius? Is there a place between either where it is physically closer to present ground level or as close to present ground level in which there is a clear physical indication of this having been closer to surfaces since then eroded?

Middle Jurassic is also supposed to be earlier than Upper Jurassic. So where does Isalo III Formation, Madagascar, Middle Jurassic (Bathonian) get us?

We have an Archosaur and two Sauropoda (Behemoths, on Kent Hovind's view). Razanandrongobe sakalavae (Archosauria), Archaeodontosaurus descouensi (Sauropoda), Lapparentosaurus madagascariensis (Sauropoda Macronaria Brachiosauridae).

Question part 5 : is Brachopterygius found above any of these at least three specimina?

Because, if all parts of the question can be summed up as "no", I think where Brachopterygius was found was pre-Flood sea, where the other creatures were found was pre-Flood land.
