Barret, P.M. 2005. The diet of ostrich dinosaurs (Theropoda:
Ornithomimosauria). _Palaeontology_ 48(2):347-358.
"The diets of ornithomimosaurian dinosaurs (Theropoda:
have proved to be contentious owing to a dearth of unambiguous evidence
in support of carnivory, omnivory or herbivory. Re-assessment of
anatomical, taphonomical and palaeoecological evidence, and estimates
daily minimal energy budgets for two derived ornithomimosaurian genera,
indicate that suspension-feeding and carnivory were unlikely. The
combined presence of a keratinized rhamphotheca and gastric mill is
strongly indicative of a herbivorous habitus for these dinosaurs.
Herbivorous and omnivorous forms are rare among the non-avian
but are more common than previously suspected. Rejection of carnivorous
habits for derived ornithomimosaurs redresses apparent discrepancies in
the relative abundances of the herbivore and carnivore guilds of
Late Cretaceous faunas."
Jouve, S., B. Bouya and M. Amaghzaz. 2005. A short-snouted dyrosaurid
(Crocodyliformes, Mesoeucrocodylia) from the Palaeocene of Morocco.
"This paper describes a new genus and species of dyrosaurid,
*Chenanisuchus lateroculi* gen. et sp. nov. (Crocodyliformes,
Mesoeucrocodylia) from the Thanetien (Late Palaeocene) of the Oulad
Abdoun Basin, Morocco. This new taxon has a particularly short snout,
well as widely separated and laterally facing orbits. In the holotype,
the mandible exhibits a retroarticular process that is strongly
depressed posterior to the glenoid fossa, bringing the ventral margin
the medial wing of the articular to the same level as the ventral
of the retroarticular process. This feature is shared with *Congosaurus
bequaerti*, *Dyrosaurus* and isolated dyrosaurid material from Mali and
Niger, but is absent in the putative closely related crocodyliforms,
such as pholidosaurids and *Terminonaris*, and could be a dyrosaurid

Little steps are often the hardest to take. We are too used to making leaps
in the face of adversity, that a simple skip is so hard to do. We should all
learn to walk soft, walk small, see the world around us rather than zoom by it.
