-- Per George M. Lane: “Nasals changed their place of articulation to that of the following consonant. Thus, dental n before the labials p and b became the labial m... labial m before the gutturals c and g became guttural n...labial m before the dentals t, d, s became dental n…” (§164.3); “One nasal, n, is assimilated to another, m...but an m before n is never assimilated..." (§166.5). -- Per Lloyd (1987: 84): “The opposition between nasals was neutralized in syllable-final position, with the realization of the nasality being assimilated to the point of articulation of the following consonant, e.g., [m] is found only before labials, [n] only before dentals or alveolars, and [ŋ] only before velars and /n/."

-- Allophones of /l/
{"l", "ɫ̪"},
-- “Pinguis”. Dark/velarized.
-- Per Weiss (2009: 117): “…pinguis (velar). l is exīlis before i and when geminate, otherwise l is pinguis.”
-- Page 82: “…l is pinguis even before e, e.g. Herculēs < Hercolēs … < Hercelēs …”
-- Per Sihler (1995: 174): “l exilis was found before the vowels -i- and -ī-, and before another -l-; l pinguis occurred before any other vowel; before any consonant except l; and in word-final position […] l pinguis actually had two degrees of avoirdupois, being fatter before a consonant than before a vowel…”
-- Page 41: “…velarized l (that is, ‘l pinguis’)…”
-- Sen (2015: §2) states that /l/ was velarized in word-final position or before consonants–other than another /l/–and that it had varying degrees of “dark resonance (velarization in articulatory terms)” (p. 23) before e, a, o, and u (p. 33).
-- Both Sen and Sihler indicate different degrees of velarization, depending on the environment. IPA lacks a way to represent these gradations, unfortunately.
{"ɫ̪([.ˈ]?)ɫ̪", "l%1lʲ"},
{"ɫ̪([.ˈ]?[iɪyʏ])", "lʲ%1"},
-- “Exīlis”. Not dark/velarized. Possibly palatalized.
-- Per Sen (2015: 29): It is plausible […] that simple onset /l/ was palatalized before /i/, thus [lʲ] […] it seems likely that geminate /ll/ was also palatalized, given the similar behaviour of the two…”
-- Per Weiss (2009: 82): “In Latin, l developed…a non-velar (possibly palatal) allophone called exīlis before i and when geminate…”
-- Per Sihler (1995: 174): “l exilis was found before the vowels -i- and -ī-, and before another -l-.”
-- Per Sihler (2000: §133.1): "It is less clear whether the 'thin' lateral [i.e. L exilis] was specifically palatal, or palatalized, or only neutral."
-- Giannini and Marotta apparently argue that it was not palatalized (https://i.imgur.com/ytM1QDn.png). I do not have access to the book in question.
-- Retracted /s/
{"s", "s̠"},
-- Lloyd (1987: 80–81) expresses some uncertainty about this, but appears to overall be in favour of it: “…the evidence that the apico-alveolar pronunciation was ancient in Latin and inherited from Indo-European is quite strong.”
-- Per Zampaulo (2019: 93), “…in many instances, Latin s was likely pronounced as an apical segment [s̺] (rather than laminal [s])."
-- Per Widdison (1987: 64), "In all, it would be fair to state that the apico-alveolar [ś] articulation represented the main allophonic variant of Latin and possibly IE /s/..."
