Fasolasuchus tenax skull by bLAZZE92 Fasolasuchus tenax skull by bLAZZE92

Reconstruction of the skull of Fasolasuchus tenax, is a composite of the known cranial bones, the premaxilla of the holotype (PVL 3850) and the maxilla and dentary from the referred specimen PVL 3851. Based on photos and drawings in Nesbitt et al. (2013) and Bonaparte (1981), other than the length of the maxilla no other measurement is mentioned so for the dentary I had to go with the scalebar alone. The scale of the premaxilla is based on the proportions of Postosuchus kirkpatricki, the rest of the skull is reconstructed after Batrachotomus kupferzenllensis with a bit of Postosuchus here and there to reflect its phylogenetic position. 

 Total skull length estimated at ~91cm.

Basado en fotos y dibujos en Nesbitt et al. (2013) y Bonaparte (1981), a excepción del largo del maxilar no se menciona ninguna otra medida así que en el caso del dentario tuve que confiar en la barra de escala. La escala del premaxilar está basada en las proporciones de Postosuchus kirkpatricki, el resto del cráneo fue reconstruido en base a Batrachotomus kupferzenllensis con un poco de Postosuchus por aquí y por allá para reflejar su posición filogenética.

 Largo total del cráneo estimado en ~91cm.

Around 7m, I explained how I got that in earlier comments, sorry for the super late reply.

thank you for answering my random question.

it appears this specimen isn't well studied at all for some reason.

It's pretty incomplete, I guess is just not remarkable enough to be very studied.

not even for its (reported) size?

Even ignoring that pieces of mandible, ribs and a couple of vertebrae are not enough for decent size estimation, I have the suspicion that it's size isn't very remarkable. Horner made those claims to the press in May of 2000, the same month that Sue went to public display in the Field Museum and about 2-3 years prior to Sue's monograph. Any size comparison between the two was most likely eyeballed rather than based on concrete measurements.

About 7-8m, based on other's skeletals of Saurosuchus.

Ok, i heard someone say it was 11m

bLAZZE92 Featured By Owner May 16, 2015
I've heard that too but is incorrect, in the scientific literature there's only one estimate, of 8-10m but no details are given of how it was done, I personally don't see evidence of it even being 8m long.

There isn't that much material.

Yes, but the size of the head is a good proxy and given how the maxilla is low and elongated compared to those of other similarly derived rauisuchians I'm being generous by just doing an isometric scaling of head length.

Hola bLAZZE92

Se menciona que el cráneo sería de 1.3 metros pero esto es un error muy claro, así como también las medidas que estiman de 8 a 10 metros se me hacen poco realistas. Estimándolo con Saurosuchus a mi me da 7 metros de largo suponendo que el fémur fuese de 75 cm como publican (CASEY M. HOLLIDAY & STERLING J. NESBITT, 2013). Saurosuchus tiene un fémur de 694 mm y según lo esqueletos que he revisado no pasa de 6.5 metros.

Creo que tu estimación es muy realista, te felicito.

Fairly similar to a large Allosaurus-skull (such as AMNH 666 or 5727) in size.

Indeed, someday I'll get around doing an skeletal of it, too bad there are no precise measurements.

That same question is what drove me to make the reconstruction.

bLAZZE92 Featured By Owner Sep 18, 2013
In between homework I'm updating this reconstruction, Nesbitt 2013 has a photo of the maxilla and looks different to Bonaparte's drawing, more robust, I'm also changing the taxa in which I base the rest of the skull, Nesbitt et al. 2011 found Fasolasuchus to be more derived than Prestosuchus and Saurosuchus, being in a sister relationship to a clade compromising Rauisuchus+Polonosuchus+Postosuchus, therefore, the new reconstruction will be based mostly on Batrachotomus (one position less derived than Fasolasuchus) with some touches of Postosuchus.

Interesante, con el nuevo resultado se ve más alargado y creo que más robusto en general.

Pues de hecho quedo 2cm mas largo pero no es mucho, probablemente da esa impresión por la nueva mandibula que es mas delgada ya que este craneo es actualmente mas alto que el anterior.

I'm just guessing, but looks equal in size to Barinasuchus.
Reply
:iconblazze92:
bLAZZE92 Featured By Owner Aug 13, 2013
Who knows, Barinasuchus seems to have a "tip of the snout to the back of the skull table" length of 65cm or so, which is comparable with Saltwater crocodiles around 5m long. I'm trying to reconstruct the missing parts based on Sebecus, I'm getting something like 76cm for the total length of the skull.

Interesting, I thought that it bigger, the fossil mandibles found have 70 cm in length 2.bp.blogspot.com/-OGugvlAwJsk… although certainly it needs a comparison with the skeleton and skull of Sebecus.

Oh, and great reconstructions, keep up the good work :)

You know what? I think you're right, I had previously confused the basioccipital with the occipital condyle lol meaning that what I said in my previous comment is incorrect and I was reconstructing the missing parts too short, It seems the total length was indeed over 80cm while the standard skull measurement was above 70cm, pushing this measurement onto 6m saltie territory.

I made a comaprison of the sebecid skulls some time ago:zimices.deviantart.com/art/Seb… but I known that it's not particulary reliable, I assumed a total size of 7-8 metrs for Barinasuchus. Well, this issue of the big terrestrial pseudosuchians is plenty of surprises :)

Nice work!

How long is the skull (and body) of Saurosuchus for comparison? Is this guy really the biggest prestosuchid, and, is it really that big?

My guess would be ~8m
