Key-wordr: Odeáxere conglomerale - Aalenian - Bajocian - Algarve.

According to P. Choffat, Odeáxere conglomerate was Oxfordian in age,
and would represem the unconformity between Malm and Dogger. Choffat's opinion was based exclusively in a lithological comparison with conglomerates from Arrábida; these conglomerates are now reporred to the Dogger, as they are intercalated berween beds with Timidonella sarda.
However, in the mesogean realm, the stratigraphical position of T. sarda in the Dogger is still not accurately known. Some authors think its range would extend from Aalenian until the Bajocian, yet others think it would be more restricted, fcom Aalenian to the lower Bajocian only.
Its stratigraphical span seems to be even more restricted in Algarve :
uppermost Aalenian to lowermost Bajocian.
