_laudatus_ just is _not_ past. It show perfect aspect, but is
indifferent as regards tense.

The imperfect is certainly past and, as Andreas says, has no dental ending.

As for _laudavi_ that could be either _present_ perfect (I have praised)
or simple past (I praised); the difference between the two meanings was
felt by Classical writers in that if the so-called 'perfect tense' had a
present perfect meaning, 'primary tenses' of the subjunctive were used
in subordinate clauses; but if it had the simple past meaning, then
'historic tenses' were used. (Of course 'tenses' when referring to the
subjunctive forms did not have the strict meaning of "time reference").

The only two tenses that are unambiguously past in Latin are the
imperfect (laudabam) and the pluperfect (laudaveram) - neither has
dental endings.

And everything I've read indicates that also. As for dentals showing
past time, one may, perhaps, think of the 'weak aorist' of ancient Greek
being formed withe dental fricative [s]. But, as the subjunctive,
optative, participle & infinitives forms of the aorist clearly show,
this was an _aspectual_ marking, not one of past time. Past time per_se
in ancient Greek was marked by the prefix e- (or, if verb with a vowel,
by lengthening the vowel): the so-called 'augment'.

I am not aware of dental being a mark of past time in PIE; but I must
confess I have not kept up to date with the latest thinking on PIE. I
should welcome enlightenment.
